Document Summary

Researchers of brain biochemistry examine the effects of two fundamental groups of chemicals, neurotransmitters and hormones, on brain processes. Thalamus: regulates arousal and serves other function. Amygdala: behind and to the outer sides of the hypothalamus, has an important roles in emotion. Hippocampus: near the amygdala lies a tube-shaped structure, which is important in processing memories. Cortex (cerebral cortex): wrapped all around these inner organs, the outer layer, itself has 6 layers that differ somewhat in anatomy and function. Neocortex: the outermost layer, is the most distinctive part of the human brain (more complex and more wrinkled) The oldest source: the study of people who have suffered head injuries. )t"s possible to draw conclusions by keeping track of the specific problems caused by damage to different parts: brain stimulation. To stimulate its parts directly with electrodes to see what happens.
