Some Brain Facts
1) Babies Lose Half their Neurons at Birth
It is estimated that a baby loses about half their neurons before they are born. This process is sometimes referred to as pruning and may eliminate neurons that do not receive sufficient input from other neurons.
2) Seizures Not Limited to Epilepsy
0.5% of the general population has epilepsy. But it is estimated that one in 20 people will have at least one seizure during the course of their life. While seizures are characteristic of epilepsy, having a single seizure does not, in itself, constitute epilepsy. The effects of seizures can vary from complete loss of consciousness to mild shakes or loss of balance.
3) "Brain Attacks"
Strokes or "brain attacks" are the 3rd leading cause of death in the United States. A stroke occurs when the blood flow to the brain is disrupted. Disruption takes place either when a brain artery is blocked or when an artery explodes. Recently, exciting medical breakthroughs have been announced with respect to treating stroke.
4) Dividing the Hemispheres
Commisurotomy, the transection of the corpus callosum, is one possible treatment for patients with severe epilepsy. This procedure causes a complete split between the two hemispheres of the brain. As a result of this split, words presented to the patient's far left visual field cannot be read (alexia), and hidden objects placed into the left hand cannot be named (anomia). This is significant evidence for hemispheric specialization.
5) One human brain generates more electrical impulses in a single day than all of the world's telephones put together.
6) There are about 13,500,00 neurons in the human spinal cord.
7) The human brain reaches its full size in adolescence and begins shrinking after the age of twenty. Recent research has shown that the male brain shrinks faster than the female one, which may explain why men are more prone to problems such as memory loss.
8) The human brain has about 100,000,000,000 (100 billion) neurons, and about 1,000,000,000,000,000 nerve cell connections - more than the number of stars in the entire universe!
9) Unconsciousness will occur after 8-10 seconds after loss of blood supply to the brain.
