Vital Information:
In a person who is sleep-deprived, one part of the brain shuts down while other parts will kick in to help compensate.
Regardless of the brain's attempt to overcome sleep deprivation, a sleep-deprived person cannot perform mental tasks as well as someone who is well-rested.
For brain recovery, the early part of sleep each night is the most important.
The human brain
Every animal you can think of -- mammals, birds, reptiles, fish, amphibians -- all have brains. But the human brain is unique. It gives us the power to think, plan, speak, imagine. It is truly an amazing organ.
The brain performs an incredible number of tasks:
It controls body temperature, blood pressure, heart rate and breathing.
It accepts a flood of information about the world around you from your various senses (eyes, ears, nose, etc.).
It handles physical motion when walking, talking, standing or sitting.
It lets you think, dream, reason and experience emotions.
All of these tasks are coordinated, controlled and regulated by an organ that is about the size of a small head of cauliflower: your brain.
