  The Human Brain - Welcome
You have been entrusted with the care and feeding of the most extraordinary and complex creation in the universe.
Home to your mind and personality, your brain houses your cherished memories and future hopes.
Here you can get to know your brain – the food it likes, the challenges it craves, the rest it requires, the protection it deserves.

 Brain Basics: Know Your Brain: National Institute of Neurological Disorders and Stroke (NINDS)
The forebrain is the largest and most highly developed part of the human brain: it consists primarily of the cerebrum (2) and the structures hidden beneath it (see "The Inner Brain").
Deep within the brain, hidden from view, lie structures that are the gatekeepers between the spinal cord and the cerebral hemispheres.
The brain and the rest of the nervous system are composed of many different types of cells, but the primary functional unit is a cell called the neuron.

And the mammalian brain became the human brain by adding the massive grey matter (neocortex) which envelopes most of the earlier brain and amounts to about 85 per cent of the human brain mass.
And human emotional responses depend on neuronal pathways which link the right hemisphere to the mammalian brain which in turn is linked to the even older reptilian brain.
In the case of the brain, the connections are made by neurons that connect the sensory inputs and motor outputs with centers in the various lobes of the cortex.

 The Function of the Human Brain
The human brain was developed through a similar process, from the simple to the complex, along with the evolution of the human.
In scanning the human brain for metabolic activity while performing various functions, it appears that some preprocessing is scattered, indicating that the evolutionary development process for the function was not uniform but occurred in sporadic time episodes.
The brains from the formerly sedentary mice had become more robust with the new stimulation and the formerly robust brains had shifted to the appearance of those from the sedentary container in the first half of the experiment.

 HHMI News: Human Brain Evolution Was a 'Special Event'
Humans and macaques shared a common ancestor 20-25 million years ago, whereas rats and mice are separated by 16-23 million years of evolution.
The human brain is several times larger than that of the macaque—even after correcting for body size—and “it is far more complicated in terms of structure,” said Lahn.
In addition to uncovering the overall trend that brain-related genes—particularly those involved in brain development—evolved significantly faster in the human lineage, the study also uncovered two dozen “outlier” genes that might have made important contributions to the evolution of the human brain.

The Human Brain Project consists of two interrelated segments: new brain-viewing technology and a system of organizing brain research data.
Thus, if neurologists wanted information on a particular part of the brain, it was generally easier for them to conduct their own research rather than dig through volumes of published work.
