Your brain generates about 12-25 watts of electricity. This is enough to power a low wattage LED light bulb.
There are 86 billion neurons in the brain.
There are more than 125 trillion synapses just in the cerebral cortex alone.
Being dehydrated by just 2% impairs performance in tasks that require attention, psychomotor, and immediate memory skills, as well as assessment of the subjective sta
As little as five minutes without oxygen can cause some brain cells to die, leading to severe brain damage.
Your brain can process an image that your eyes have seen for as little as 13 milliseconds – less time than it takes for you to blink.

Celebral spinal fluid flows in and around the hollow spaces of the brain and spinal cord.
There is a great deal of neural conversation between the gut and the brain. After all, if the gut is not well fed, it could be a matter of life and death; the brain needs to be informed when energy i s low so that it can call other systems into action.
