Document Summary
The hippocampus has pattern of neural activity when the brain is learning something new, the same neural activity pattern during sleep in order to help the info stick, Loss of sleep leads to loss of long term memories. Sleep loss results in focusing on negative experiences. Unpredictable emotions may be result of interrupted brain communication between regions. May not be able to clearly articulate clever commentary. Sleep lose slows divergent thinking, activity in inferior frontal gyrus increases when sleep deprived people are tasked with listing objects. Brain draws on divergent thinking to compensate for strained cognitive functioning. Lack of sleep in individuals who are sleep deprived due to decreased activity in the frontal lobe which controls decisions making. Also, activity is decreased in the amygdala (key player in fear detection) These neural changes dull judgement and increase desire leading to bad decisions. Attention lapses changes occur when people lose sleep.
