Live Science: Human brain: Facts, functions & anatomy

By Tanya Lewis – Staff WriterAshley P. Taylor – Live Science Contributor 

The human brain is the command center for the human nervous system.

A medical illustration of the human brain from ‘Quain’s Elements of Anatomy, Eighth Edition, Vol.II’ (by William Sharpey MD, LLD, FRS L&E, Allen Thomson, MD, LLD, FRS L&E, and Edward Albert Schafer) depicts the right half of the brain, 1876. (Image credit: Vintage MedStock/Getty Images)

The human brain is the command center for the human nervous system. It receives signals from the body’s sensory organs and outputs information to the muscles. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than the brains of many other mammals, such as dolphins, whales and elephants.

HOW MUCH DOES A HUMAN BRAIN WEIGH?

The human brain weighs about 3 lbs. (1.4 kilograms) and makes up about 2% of a human’s body weight. On average, male brains are about 10% larger than female brains, according to Northwestern Medicine in Illinois. The average male has a brain volume of nearly 78 cubic inches (1,274 cubic centimeters), while the average female brain has a volume of 69 cubic inches (1,131 cubic cm). The cerebrum, which is the main part of the brain located in the front area of the skull, makes up 85% of the brain’s weight.

HOW MANY BRAIN CELLS DOES A HUMAN HAVE?

The human brain contains about 86 billion nerve cells (neurons) — called “gray matter,” according to a 2012 study published in the Proceedings of the National Academy of Sciences. The brain also has about the same number of non-neuronal cells, such as the oligodendrocytes that insulate neuronal axons with a myelin sheath. This gives axons (thin strands through which electrical impulses are transmitted between neurons) a white appearance, and so these axons are called the brain’s “white matter.”

OTHER COOL FACTS ABOUT THE BRAIN

  • The brain can’t multitask, according to the Dent Neurologic Institute. Instead, it switches between tasks, which increases errors and makes things take longer.
  • The human brain triples in size during the first year of life and reaches full maturity at about age 25.
  • Humans use all of the brain all of the time, not just 10% of it.
  • The brain is 60% fat, according to Northwestern Medicine.
  • The human brain can generate 23 watts of electrical power — enough to fuel a small lightbulb.

Do Scientists Understand The Human Brain?  | Video

“We might someday figure out how the brain works” says NYU neuroscientist Gary Marcus, co-author of “The Future of the Brain”, in this exclusive interview with Live Science’s Bahar Gholipour. Marcus breaks down the latest advancements in neuroscience and explains where these discoveries are coming from.

ANATOMY OF THE HUMAN BRAIN

The largest part of the human brain is the cerebrum, which is divided into two hemispheres, according to the Mayfield Clinic. Each hemisphere consists of four lobes: the frontal, parietal, temporal and occipital. The rippled surface of the cerebrum is called the cortex. Underneath the cerebrum lies the brainstem, and behind that sits the cerebellum.

The frontal lobe is important for cognitive functions, such as thought and planning ahead, and for the control of voluntary movement. The temporal lobe generates memories and emotions. The parietal lobe integrates input from different senses and is important for spatial orientation and navigation. Visual processing takes place in the occipital lobe, near the back of the skull.

The brainstem connects to the spinal cord and consists of the medulla oblongata, pons and midbrain. The primary functions of the brainstem include relaying information between the brain and the body; supplying most of the cranial nerves to the face and head; and performing critical functions in controlling the heart, breathing and levels of consciousness (it’s involved in controlling wake and sleep cycles).

Between the cerebrum and brainstem lie the thalamus and hypothalamus. The thalamus relays sensory and motor signals to the cortex. Except for olfaction (sense of smell), every sensory system sends information through the thalamus to the cortex, according to the online textbook, “Neuroanatomy, Thalamus” (StatPublishing, 2020). The hypothalamus connects the nervous system to the endocrine system — where hormones are produced — via the pituitary gland.

The cerebellum lies beneath the cerebrum and has important functions in motor control. It plays a role in coordination and balance and may also have some cognitive functions.

The brain also has four interconnected cavities, called ventricles, which produce what’s called cerebrospinal fluid (CSF). This fluid circulates around the brain and spinal cord, cushioning it from injury, and is eventually absorbed into the bloodstream.

In addition to cushioning the central nervous system, CSF clears waste from the brain. In what’s called the glymphatic system, waste products from the interstitial fluid surrounding brain cells move into the CSF and away from the brain, according to the Society for Neuroscience. Studies suggest this waste clearance process mostly happens during sleep. In a 2013 Science paper, researchers reported that when mice were asleep, their interstitial spaces expanded by 60%, and the brain’s glymphatic system cleared beta-amyloid (the protein that makes up Alzheimer’s disease’s hallmark plaques) faster than when the rodents were awake. Clearing potentially neurotoxic waste from the brain or “taking out the trash” through the glymphatic system could be one reason that sleep is so important, the authors suggested in their paper.

Is The Human Brain Just a Computer? One Neuroscientist Thinks So

In recent years, much of the scientific community has backed away from the ‘computational engine’ comparison, citing the brain’s extreme complexity. But NYU neuroscientist Gary Marcus, co-author of “The Future of the Brain,” thinks “we’ve given up too soon,” in this chat with Live Science’s Bahar Gholipour. PLAY SOUND

IS BRAIN SIZE LINKED TO INTELLIGENCE?

Overall brain size doesn’t correlate with level of intelligence for non-human animals. For instance, the brain of a sperm whale is more than five times heavier than the human brain, but humans are considered to be of higher intelligence than sperm whales. A more accurate measure of an animal’s likely intelligence is the ratio between the size of the brain and body size, although not even that measure puts humans in first place: The tree shrew has the highest brain-to-body ratio of any mammal, according to BrainFacts.org, a website produced by the Society for Neuroscience.

Among humans, brain size doesn’t indicate a person’s level of intelligence. Some geniuses in their field have smaller-than-average brains, while others have brains that are larger than average, according to Christof Koch, a neuroscientist and president of the Allen Institute for Brain Science in Seattle. For example, compare the brains of two highly acclaimed writers. The Russian novelist Ivan Turgenev’s brain was found to weigh 71 ounces (2,021 grams), while the brain of French writer Anatole France weighed only 36 ounces (1,017 g).

Brain size doesn’t indicate a person’s intelligence.   (Image credit: Shutterstock)

The reason behind humans’ intelligence, in part, is neurons and folds. Humans have more neurons per unit volume than other animals, and the only way they can all fit within the brain’s layered structure is to make folds in the outer layer, or cortex, said Dr. Eric Holland, a neurosurgeon and cancer biologist at the Fred Hutchinson Cancer Research Center and the University of Washington.

“The more complicated a brain gets, the more gyri and sulci, or wiggly hills and valleys, it has,” Holland told Live Science. Other intelligent animals, such as monkeys and dolphins, also have these folds in their cortex, whereas mice have smooth brains, he said.

How the brain is integrated also seems to matter when it comes to intelligence. A genius among geniuses, Albert Einstein had an average size brain; researchers suspect his mind-boggling cognitive abilities may have stemmed from its high connectivity, with several pathways connecting distant regions of his brain, Live Science previously reported.

Humans also have the largest frontal lobes of any animal, Holland said. The frontal lobes are associated with higher-level functions such as self-control, planning, logic and abstract thought — basically, “the things that make us particularly human,” he said.

WHAT’S THE DIFFERENCE BETWEEN THE LEFT BRAIN AND RIGHT BRAIN?

The human brain is divided into two hemispheres, the left and right, connected by a bundle of nerve fibers called the corpus callosum. The hemispheres are strongly, though not entirely, symmetrical. Generally, the left brain controls the muscles on the right side of the body, and the right brain controls the left side. One hemisphere may be slightly dominant, as with left- or right-handedness.

Related: What’s the difference between the right brain and the left brain?

The popular notions about “left brain” and “right brain” qualities are generalizations that are not well supported by evidence. However, there are some important differences between these areas. The left brain contains regions that are involved in language production and comprehension (called Broca’s area and Wernicke’s area, respectively) and is also associated with mathematical calculation and fact retrieval, Holland said. The right brain plays a role in visual and auditory processing, spatial skills and artistic ability — more instinctive or creative things, Holland said — though these functions involve both hemispheres. “Everyone uses both halves all the time,” he said.

The human brain has two hemispheres, which are popularly considered to be responsible for completely different set of skills, but there’s little scientific research to support that notion.  (Image credit: Dimitri Otis/Getty Images)

BRAIN INITIATIVE

In April 2013, President Barack Obama announced a scientific grand challenge known as the BRAIN Initiative, short for Brain Research through Advancing Innovative Neurotechnologies. The $100-million-plus effort aimed to develop new technologies to produce a dynamic picture of the human brain, from the level of individual cells to complex circuits.

Like other major science efforts, such as the Human Genome Project, the significant expense is usually worth the investment, Holland said. Scientists hope the increased understanding will lead to new ways to treat, cure and prevent brain disorders.

The project contains members from several government agencies, including the National Institutes of Health (NIH), the National Science Foundation (NSF) and the Defense Advanced Research Projects Agency (DARPA), as well as private research organizations, including the Allen Institute for Brain Science and the Howard Hughes Medical Institute.

In May 2013, the project’s backers outlined their goals in the journal Science. In September 2014, the NIH announced $46 million in BRAIN Initiative grants. Industry members pledged another $30 million to support the effort, and major foundations and universities also agreed to apply more than $240 million of their own research toward BRAIN Initiative goals.

When the project was announced, President Obama convened a commission to evaluate the ethical issues involved in research on the brain. In May 2014, the commission released the first half of its report, calling for ethics to be integrated early and explicitly in neuroscience research, Live Science previously reported. In March 2015, the commission released the second half of the report, which focused on issues of cognitive enhancement, informed consent and using neuroscience in the legal system, Live Science reported.

The Brain Initiative has achieved several of its goals. As of 2018, the NIH has “invested more than $559 million in the research of more than 500 scientists,” and Congress appropriated “close to $400 million in NIH funding for fiscal year 2018,” according to the initiative’s website. The research funding facilitated the development of new brain-imaging and brain-mapping tools, and helped create the BRAIN Initiative Cell Census Network (BICCN) — an effort to catalog the brain’s “parts’ list.” The BICCN released its first results in November 2018.

Beyond a parts list, the BRAIN Initiative is working to develop a detailed picture of the circuits in the brain. For example, in 2020, BRAIN Initiative researchers published a study in the journal Neuron, reporting that they had developed a system, tested in mice, to control and monitor circuit activity at any depth in the brain. Previous efforts could only examine circuits close to the surface of the brain. Also in 2020, the initiative’s Machine Intelligence from Cortical Networks (MICrONS) program, an effort to map circuits in the cortex, launched a website where researchers can share their data, including electron microscopy images of circuits.

Since 2019, the initiative has sponsored a photo and video contest in which initiative researchers are invited to submit eye-catching depictions of the brain. Check out the 2020 winners on the Brain Initiative website.

DOES THE BRAIN STAY ALIVE AFTER A PERSON DIES?

April 2019 marked a milestone for both the initiative and neuroscience research at large: BRAIN Initiative researcher Nenad Sestan, of the Yale School of Medicine, published a report in the journal Nature, revealing that his research team had restored circulation and some cellular functions to pig brains four hours after the animals’ deaths, Live Science previously reported. The results challenged the prevailing view that brain cells are suddenly and irreversibly damaged shortly after the heart stops beating. The researchers did not observe any signs of consciousness in the brains, nor were they trying to; on the contrary, the researchers injected pig brains with chemicals that mimicked blood flow and also blocked neurons from firing. The researchers emphasized that they did not bring the pig brains back to life. They did, however, restore some of their cellular activity.

Larval fish of Dendrochirus, all images copyright Ryo Minemizu

Japanese marine life photographer Ryo Minemizu focuses his lens on some of the tiniest and most abundant life forms in our oceans. His series Phenomenons explores the diverse beauty and extravagant colors of plankton, and is shot amongst the dark waters of the Osezaki sea near Mount Fuji and other coasts around Japan, the Philippines and Maldives. To capture the small creatures Minemizu sets his shutter speed to just a fraction of a second, while ensuring that his own movements don’t disturb the surrounding organisms.

“Plankton symbolize how precious life is by their tiny existence,” he explains. “I wanted other people to see them as they are in the sea, so it was my motivation from the beginning to shoot plankton underwater, which is quite a challenge. Most plankton are small, and their movements are hard to predict.”

His solo exhibition Jewels in the Night Sea begins a three-city tour at Canon Gallery in Ginza, Tokyo from August 20-29, 2018. It will then move to Cannon galleries in Nagoya and Osaka from September 6-12 and September 20-26, 2018. You can see more of Minemizu’s underwater photography on Instagram and Twitter. Select prints from his Phenomenons series are available in his online shop. (via This Isn’t Happiness)

President Joe Biden will address a joint session of Congress for the first time on April 28. Speaker of the House Nancy Pelosi extended the invitation to Biden, “to share your vision for addressing the challenges and opportunities of this historic moment.” The speech will come just before Biden’s 100th day in office, and will provide him an opportunity to update the American public on his progress toward fulfilling his promises. It will also give him a chance to make the case for the $2.3 trillion infrastructure package he unveiled earlier this month, which the House is aiming to pass by July 4. Traditionally all members of Congress and guests gather for a joint session in the House, the larger of the two chambers. However, the address is certain to look different this year due to the coronavirus pandemic. Stream your PBS favorites with the PBS app: https://to.pbs.org/2Jb8twG?

Toxic waste dump site more than twice the size of Manhattan discovered in Pacific Ocean

Apr 27, 2021  PBS NewsHour

A massive underwater toxic waste site has long been suspected off the Southern California shore, since industrial companies used the ocean as a dumping ground until 1972. Now marine scientists have identified over 25,000 barrels they believe contain the toxic chemical “DDT” in the Pacific Ocean. Stephanie Sy talks to David Valentine, a UC Santa Barbara professor of microbiology, about the barrels. Stream your PBS favorites with the PBS app: https://to.pbs.org/2Jb8twG?

Alice Neel: They Are Their Own Gifts, 1978 | From the Vaults

Dec 18, 2020  The Met

A self-proclaimed “collector of souls,” the American painter Alice Neel (1900–1984) is known today for her powerful, psychologically rich portraiture. She depicted a wide range of subjects, from her family and friends to prominent critics, artists, activists, and strangers she met on the street. In this rarely seen documentary, Neel’s signature candor and wit are on full display. Providing a brief biographical sketch from her early marriage and the Great Depression through her later years in Spanish Harlem, the film also shows the artist at work on a portrait of Lucille Rhodes, who co-directed with Margaret Murphy. Excerpted from Rhodes and Murphy’s “They Are Their Own Gifts” (1978), a triptych of “film portraits” about women artists that also includes chapters on the poet and activist Muriel Rukeyser as well as the dancer and choreographer Anna Sokolow. Cinematography by the legendary Babette Mangolte. Learn about The Met’s upcoming exhibition on Alice Neel: https://www.metmuseum.org/exhibitions…?

Nationality American
Known for Painting

Alice Neel (January 28, 1900 – October 13, 1984) was an American visual artist, who was known for her portraits depicting friends, family, lovers, poets, artists, and strangers. Her paintings have an expressionistic use of line and color, psychological acumen, and emotional intensity. Her work depicts women through a female gaze, illustrating them as being consciously aware of the objectification by men and the demoralising effects of the male gaze.[1] Her work contradicts and challenges the traditional and objectified nude depictions of women by her male predecessors.[1] Neel was called “one of the greatest portrait artists of the 20th century” by Barry Walker, curator of modern and contemporary art at the Museum of Fine Arts, Houston, which organized a retrospective of her work in 2010

Transcript:

What’s Up for May? This month, a rocky planet round-up, and a super blood Moon eclipse!

Beginning mid-May, if you can find a clear view toward the western horizon, you’ll have an opportunity to see all four of the rocky, inner planets of our solar system at the same time, with your own eyes. Starting around May 14th, cast your gaze to the west about half an hour after sunset, local time to see if you can spot Mercury, Venus, and Mars. (And well, Earth is kind of hard to miss.)

To see near the horizon, you need an unobstructed view – free of nearby trees and buildings. Some of the best places for this are the shores of lakes or the beach, open plains, or high up on a mountain or tall building.

In addition to the planets, from around the 14th through the 17th, the crescent Moon joins the party for a lovely planetary tableau. Now, Venus will be really low in the sky. (It’ll be easier to observe on its own later in the summer.) But for now, take advantage of this opportunity to observe all of the inner planets in a single view.

May 26 brings a total lunar eclipse. Over several hours, the Moon will pass through Earth’s shadow, causing it to darken and usually become reddish in color. The red color comes from sunlight filtering through Earth’s atmosphere – a ring of light created by all the sunrises and sunsets happening around our planet at that time Because of the reddish color, a lunar eclipse is often called a “blood moon.” Just how red it will look is hard to predict, but dust in the atmosphere can have an effect. (And keep in mind there have been a couple of prominent volcanic eruptions recently.)

Lunar eclipses take place when the Moon is full, and this full Moon happens when the Moon is also near its closest point to Earth in its orbit, often called a “supermoon.”

Unlike solar eclipses, which you should never look at, it’s safe to view lunar eclipses with your eyes. And unlike solar eclipses, which tend to have a narrower viewing path, lunar eclipses are at least partly visible anywhere on the planet’s night side.

Now, eclipses happen at the same moment no matter where you are on Earth, but what time your clock reads during the eclipse depends, of course, on your time zone. The best viewing for this eclipse is in the Pacific Rim – that’s the western parts of the Americas, Australia and New Zealand, and Eastern Asia. For the U.S., the best viewing will be in Hawaii, Alaska, and the western states.

For the Eastern U.S., the eclipse begins for you during dawn twilight. You may be able to observe the first part of the eclipse as the Moon just starts to darken, but the Moon will be near or on the horizon as Earth’s shadow begins to cover it. The farther west you are, the more of the eclipse you’ll be able to see before the Moon sets that morning. Those in the western half of the country will be able to see almost the entire eclipse.

So if you’re in the path of this eclipse, check your local times for the best viewing near you. And if you’re in the U.S., be prepared to get up early if you want to see this rare celestial event: a super blood moon eclipse.

Here are the phases of the Moon for May.

You can catch up on all of NASA’s missions to explore the solar system and beyond at nasa.gov. I’m Preston Dyches from NASA’s Jet Propulsion Laboratory, and that’s What’s Up for this month.

NASA’s Ingenuity Mars Helicopter became the first aircraft in history to make a powered, controlled flight on another planet on April 19, 2021. The Ingenuity team at NASA’s Jet Propulsion Laboratory in Southern California determined that the flight was successful after receiving data from both the helicopter and the Perseverance Mars rover.

Ingenuity is a technology demonstration. The 19-inch-tall Ingenuity Mars Helicopter contains no science instruments. Instead, the 4-pound rotorcraft will help determine whether future explorations on Mars could be conducted from the air.

Perseverance touched down at Octavia E. Butler Landing with Ingenuity attached to its belly on Feb. 18. The helicopter was deployed to the surface of Jezero Crater on April 3.

Transcript:

[Marina Jurica] Earlier today, Ingenuity should have autonomously performed its first flight attempt on Mars. Now, the team is ready to receive the data that will tell them whether we’ve made history.

[VOCA] This is downlink. We are beginning to see data products.

[VOCA] Rotor motors appear healthy, all actuators appear healthy.

[VOCA] Ingenuity is reporting having performed spin up, take off, climb, hover, descent, landing, touchdown and spin down.

[VOCA] Altimeter data confirmed that Ingenuity has performed its first flight.

[cheers, clapping]

[VOCA] First flight of a powered aircraft on another planet.

[cheers, clapping]

[MiMi Aung] We can now say human beings have flown a rotorcraft on another planet. Let’s get back to work and more flights! Congratulations!

The shadow of NASA’s Ingenuity Mars Helicopter can be seen in this animated GIF composed of images taken by its black-and-white navigation camera during the rotocraft’s third flight, on April 25, 2021.

This is the third color image taken by NASA’s Ingenuity helicopter. It was snapped on the helicopter’s second flight, on April 22, 2021, from an altitude of about 17 feet (5.2 meters). Tracks made by NASA’s Perseverance Mars rover can be seen as well.

NASA’s Ingenuity Mars Helicopter can be seen hovering during its third flight on April 25, 2021, as seen by the left Navigation Camera aboard NASA’s Perseverance Mars rover.

The downward-looking navigation camera aboard NASA’s Ingenuity Mars Helicopter took this image of the rotorcraft’s shadow on the surface of Jezero Crater during helicopter’s second experimental test flight on April 22, 2021. The helicopter’s navigation camera autonomously tracks the ground during flight.

The Ingenuity Mars Helicopter was built by JPL, which also manages this technology demonstration project for NASA Headquarters. It is supported by NASA’s Science Mission Directorate, Aeronautics Research Mission Directorate, and Space Technology Mission Directorate. NASA’s Ames Research Center and Langley Research Center provided significant flight performance analysis and technical assistance during Ingenuity’s development.

A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust).

Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.

The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.

JPL, which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.
