44 Facts About Human brain

Human brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system.

The Human brain is contained in, and protected by, the skull bones of the head.

However, the Human brain is still susceptible to damage, disease, and infection.

The Human brain is susceptible to degenerative disorders, such as Parkinson's disease, dementias including Alzheimer's disease, and multiple sclerosis.

The Human brain can be the site of tumours, both benign and malignant; these mostly originate from other sites in the body.

Study of the anatomy of the Human brain is neuroanatomy, while the study of its function is neuroscience.

The medical history of people with Human brain injury has provided insight into the function of each part of the Human brain.

In science fiction, Human brain transplants are imagined in tales such as the 1942 Donovan's Brain.

The living Human brain is very soft, having a gel-like consistency similar to soft tofu.

Cerebrum is the largest part of the Human brain, and is divided into nearly symmetrical left and right hemispheres by a deep groove, the longitudinal fissure.

The surface of the Human brain is folded into ridges and grooves (sulci), many of which are named, usually according to their position, such as the frontal gyrus of the frontal lobe or the central sulcus separating the central regions of the hemispheres.

These areas receive input from the sensory areas and lower parts of the Human brain and are involved in the complex cognitive processes of perception, thought, and decision-making.

Human brain is primarily composed of neurons, glial cells, neural stem cells, and blood vessels.

The adult human brain is estimated to contain 86±8 billion neurons, with a roughly equal number of non-neuronal cells.

The Human brain has two main networks of veins: an exterior or superficial network, on the surface of the cerebrum that has three branches, and an interior network.

These smallest of blood vessels in the Human brain, are lined with cells joined by tight junctions and so fluids do not seep in or leak out to the same degree as they do in other capillaries; this creates the blood–Human brain barrier.

The motor system of the Human brain is responsible for the generation and control of movement.

The Human brain receives and interprets information from the special senses of vision, smell, hearing, and taste.

Autonomic functions of the Human brain include the regulation, or rhythmic control of the heart rate and rate of breathing, and maintaining homeostasis.

Sleep is an essential requirement for the body and Human brain and allows the closing down and resting of the body's systems.

Study on how language is represented, processed, and acquired by the Human brain is called neurolinguistics, which is a large multidisciplinary field drawing from cognitive neuroscience, cognitive linguistics, and psycholinguistics.

Cerebrum has a contralateral organisation with each hemisphere of the Human brain interacting primarily with one half of the body: the left side of the Human brain interacts with the right side of the body, and vice versa.

Thus, the right side of the Human brain receives somatosensory input from the left side of the body, and visual input from the left side of the visual field.

Attempts to localize basic emotions to certain Human brain regions have been controversial; some research found no evidence for specific locations corresponding to emotions, but instead found circuitry involved in general emotional processes.

Brain metabolism normally relies upon blood glucose as an energy source, but during times of low glucose, the Human brain uses ketone bodies for fuel with a smaller need for glucose.

The Human brain mostly uses glucose for energy, and deprivation of glucose, as can happen in hypoglycemia, can result in loss of consciousness.

The Human Connectome Project was a five-year study launched in 2009 to analyse the anatomical and functional connections of parts of the brain, and has provided much data.

Information about the structure and function of the human brain comes from a variety of experimental methods, including animals and humans.

The data that has been provided on gene expression in the Human brain has fuelled further research into a number of disorders.

Normal development of the Human brain can be affected during pregnancy by nutritional deficiencies, teratogens, infectious diseases, and by the use of recreational drugs, including alcohol.

When Human brain death is suspected, reversible differential diagnoses such as, electrolyte, neurological and drug-related cognitive suppression need to be excluded.

The relationship between the Human brain and the mind is a significant challenge both philosophically and scientifically.

However, when the brain-to-body mass ratio is taken into account, the human brain is almost twice as large as that of a bottlenose dolphin, and three times as large as that of a chimpanzee.

The 1942 science-fiction book Donovan's Brain tells the tale of an isolated Human brain kept alive in vitro, gradually taking over the personality of the book's protagonist.

The hieroglyph for Human brain, occurring eight times in this papyrus, describes the symptoms, diagnosis, and prognosis of two traumatic injuries to the head.

Human brain reasoned that humans are more rational than the beasts because, among other reasons, they have a larger brain to cool their hot-bloodedness.

Human brain concluded that, as the cerebellum was denser than the brain, it must control the muscles, while as the cerebrum was soft, it must be where the senses were processed.

Galen further theorized that the Human brain functioned by movement of animal spirits through the ventricles.

Vesalius rejected the common belief that the ventricles were responsible for brain function, arguing that many animals have a similar ventricular system to humans, but no true intelligence.

Human brain suggested that the pineal gland was where the mind interacted with the body, serving as the seat of the soul and as the connection through which animal spirits passed from the blood into the brain.

Human brain wrote Cerebri Anatome in 1664, followed by Cerebral Pathology in 1667.

Studies of the Human brain became more sophisticated with the use of the microscope and the development of a silver staining method by Camillo Golgi during the 1880s.

Human brain used microscopy to uncover many cell types, and proposed functions for the cells he saw.

Human brain has many properties that are common to all vertebrate brains.
