Human brain

The human brain is the center of the central nervous system in humans as well as the primary control center for the peripheral nervous system.

The brain controls "lower" or involuntary activities such as heartbeat, respiration, and digestion - these are known as autonomic functions.

The brain also controls "higher" order, conscious activities, such as thought, reasoning, and abstraction.

3D Human Brain Map Points Way to Future Discovery

3D Human Brain Map Points Way to Future Discovery

Reuters (July 16, 2013) German and Canadian scientists have built a three dimensional map of the human brain to help in the development of new treatments for neurological disorders like Alzheimer's and Parkinson's disease. The "human brain map" shows the organ in unprecedented detail, allowing neuro-researchers to examine brain function and pathways on a molecular level. Rob Muir reports.

Stanford Scientists Bring Clarity to Mouse Brain

Reuters (Apr. 11, 2013) Researchers at Stanford University in California have developed a process that renders an intact mouse brain transparent. By replacing the opaque fatty components in the brain with a transparent hydrogel, the wiring and molecular structure of the brain become clear to see with visible lite and chemicals. The research opens a door to new imaging techniques that could potentially be applied to human organs.

Exercise Keeps Older Brains in Shape

Exercise Keeps Older Brains in Shape

Deutsche Welle (Aug. 4, 2013) A healthy brain just keeps getting better with age. That is the surprising discovery of Ernst Poeppel, a brain researcher in Munich. Vocabulary, verbal memory and spacial and associative reasoning reach peak performance between the ages of 40 and 56. Ernst Poeppel says young and old brains show very little difference. So there's no reason they can't function optimally a whole life long - provided they're kept in shape like muscles. They can even grow new brain cells. The neuro-networks and transmitters, on the other hand, can get a bit rusty with age.
