Document Summary

Nuclear structures (there are a lot but these are the important ones): Basal ganglia (clump of cells, involved in motor functions, when it loses dopamine it causes parkinson"s disease) Amygdala (involved in fear; bigger amygdala more fear you feel) Old cortex (less than 5 layers, covers brain) Hippocampus (involved in converting short term memories into long term memories) Neurological patient called hm lost both sides of hippocampus when trying to cure epilepsy; couldn"t hold memories. Neocortex (more than 5 layers, 80% of human brain) This is the biggest difference between our brains and monkeys; ours is bigger. Four lobes (in each hemisphere of brain): Frontal (half of neocortex; contains some association cortex- ability to learn language in broca"s and wernicke"s area) Last part of brain to fully mature (mid 20s) Phineas gauge- shot rod through head to frontal lobe and survived but became a worse person than he was before.
