The largest part of the human brain is the cerebrum, which is divided into two hemispheres.
Like all vertebrate brains, the human brain develops from three sections known as the forebrain, midbrain and hindbrain. The cerebral cortex is greatly enlarged in human brains, and is considered the seat of complex thought.
The main differences between human and animals brains is their size, said Eric Holland, a neurosurgeon and cancer biologist at the Fred Hutchinson Cancer Research Center and the University of Washington, in Seattle. The human brain is divided into two hemispheres, the left and right, connected by a bundle of nerve fibers called the corpus callosum. 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 project contains members from several government agencies, including the National Institutes of Health (NIH), National Science Foundation (NSF), and Defense Advanced Research Projects Agency (DARPA), as well as private research organizations, including the Allen Institute for Brain Science in Seattle, Washington, and the Howard Hughes Medical Institute in Chevy Chase, Maryland. When the project was announced, President Obama convened a commision to evaluate the ethical issues involved in research on the brain. Human Brain is the center of Nervous System which control and coordinate all the functions of human body. The functions and importance of brain were discovered even in ancient time by Hippocrates, but still there are some interesting facts and mysterious functions of brain that most of us don’t know. Brain comprises a smaller portion of total body weight (only 2% weighing 3 pounds or 1.4 Kg) but it consumes largest portion of energy generated in human body.
It’s nearly hard to tickle yourself because Cerebellum (part of brain) actively monitors and anticipating touch sensations. He joined Barton Associates in 2012 after spending four years as an editor at HCPro, a national healthcare publishing company. The thalamus relays sensory and motor signals to the cortex and is involved in regulating consciousness, sleep and alertness.
Humans also have more neurons per unit volume than other animals, and the only way to do that with the brain's layered structure is to make folds in the outer layer, or cortex, 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. The $100-million-plus effort aims to develop new technologies that will produce a dynamic picture of the human brain, from the level of individual cells to complex circuits. Scientists hope the increased understanding will lead to new ways to treat, cure and prevent brain disorders. In May 2014, the commission released the first half of its report, calling for ethics to be integrated early and explicitly in neuroscience research.


It is an extremely powerful and sophisticated organ that stores our memory, control emotions, our feelings and the way we think and react. It consumes 20% of total blood oxygen, 25% of blood glucose and to fulfill these requirements, Brain receives 15 to 20% blood (750 to 1000 ml) from total cardiac output in a minute.
Human brain contain approximately 100 billion neurons (15 times greater in number than total human population) the length of these neurons range from few micrometer to 100 cm (1 meter). The right side of the brain actually controls the functions and movements of left side of body while left side of the brain controls the right side of body.
A good example of this phenomenon is that the brain constantly ignores our nose while we can always see it. Every time we remember something new or have a new thought, our brain creates new connections in itself. In case when you about to tickle yourself, Cerebellum warn the rest of the brain about what’s going on. It is accountable for everything you do- waking in the morning, recalling who you are and where you live and thoughts of love, pleasure or sorrow. Every time you have a thought you are creating new connections (neural pathways) in your brain. While awake, your brain generates between 10 and 23 watts of power or more than  energy to power a light bulb.
Laughing at a joke is no simple task as it requires activity in five different areas of the brain.
It is estimated that the human brain has a raw computational power between 10 power(13) and 10 Power(16) operations per second.
The human brain has the same basic structure as other mammal brains, but is larger in relation to body size than any other brains. The outermost layer of the cerebrum is the cerebral cortex, which consists of four lobes: the frontal lobe, the parietal lobe, the temporal lobe and the occipital lobe. The temporal lobe processes sound and language, and includes the hippocampus and amygdala, which play roles in memory and emotion, respectively.
The left brain controls all the muscles on the right-hand side of the body; and the right brain controls the left side. Members of industry 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.
In March 2015, the commission released the second half of the report, which focused on issues of cognitive enhancement, informed consent and neuroscience and the legal system. She received a graduate certificate in science communication from the University of California, Santa Cruz, and a bachelor of science in biomedical engineering from Brown University.


The total length of these neurons, if lined up end to end, would be 5000 kilometer (if multiply 100 billion with an average length of 50 micrometers). Similarly, the upper parts of body are controlled by lower portion of brain while the lower parts and organs are directed by upper areas in brain. To prove this fact with reality, pick a small object near you or a spot on wall and trying to star on it for a few second without blinking your eyes.
If you ignore and don’t follow these instruction from your brain while still stay awake, you will go into the state of sleep paralysis and will begin lucid dreaming.
Repeating or rehearsal continually stronger the connections while these connections can become weekend over time result in forgetting of memory. On average, human have approximately 70,000 thoughts, speaks 7,000 to 16,000 words and blinks eyes 12,000 times each day.
The weight of Albert Einstein’s brain was 1,230 grams that is less than an average weight of the human brain. The parietal lobe integrates input from different senses and is important for spatial orientation and navigation. She has previously written for Science News, Wired, The Santa Cruz Sentinel, the radio show Big Picture Science and other places. This huge number of neurons is supplied by numerous smaller blood vessels, the total length of which, if stretched out, would wrap around the World four times (100,000 kilometer). The person who has their right side of brain dominated over left side tend to use their left side of body. Tanya has lived on a tropical island, witnessed volcanic eruptions and flown in zero gravity (without losing her lunch!). The awareness level of human brain varies from person to person but there are some interesting brain facts that are astonishing and worth knowing.
To be exact, the brain consumes 20% of that energy despite the fact that it only represent 2% of the total body weight. About 60% of the human brain is comprised of fat which is the maximum concentration of fat that is present in a only organ in a healthy human being. The similar hormone is released during and after giving birth to help a mother link with her child. Well said by Leonardo Bianchi, Human brain is able to execute numerous tasks naturally and is considered the most multifarious organ of the body Facebook Prev Article Next Article You may also like 10 Interesting Facts About Human Body 10 Interesting Facts About Muscles 10 Interesting Facts About Fingers 10 Interesting Facts About Skin 10 Interesting Facts About Blood 10 Interesting Facts About Stomach 10 Interesting Facts About Nails 10 Interesting Facts About Eyes 10 Interesting Facts About Mouth Add Comment Cancel reply Notify me of follow-up comments by email.
