Do We Need Sleep - 1051 Words

What exactly goes on in the brain during sleep? Nerve-signaling chemicals called neurotransmitters, control whether we are asleep or awake by acting on different groups of nerve cells, or neurons, in the brain. Neurons in the brainstem, which connects the brain with the spinal cord, produce neurotransmitters such as serotonin and norepinephrine that keep some parts of the brain active while we are awake (http://www.ninds.nih.gov/disorders/brain_basics/understanding_sleep.htm). So why do we need sleep? Sleep is important to the essence of every person. Sleep offers the brain an opportunity to sort through new and old information, to find solutions to problems, and to archive memories.

The brain reinforces memory and categorizes everything learned and removes any useless information. This paper will cover how lack of sleep can be detrimental to a person.
