Document Summary
Classical (pavlovian) conditioning where neutral stimulus is paired with unpleasant experience. Amygdala processing fear: low road (very fast processing, sensory receptors thalamus amygdala, allows for immediate reaction to fearful stimuli, high road. Allows for slower interpretation, incorporates memory (recalling information about stimuli that would cause fear) Breaking relation of neutral stimulus to fear stimulus by repeated exposure to only the neutral stimulus. Mice missing one type of cannabinoid receptor have a harder time extinguishing fear responses, suggesting that enhanced cannabinoid receptor activity could treat fear conditions. Aggression primarily the physical aggression & violence between individuals (not including predation. Intermale aggression: between males of the same species. Human males 5x more likely to murder than women, suggests possible androgens correlation. The most aggressive monkeys in a free ranging colony had lowest levels of serotonin (negative correlation) Locusts that form swarms have heightened serotonin (locusts normally avoid each other) Emotional dyscontrol syndrome temporal lobe disorders tht may underlie some human violence.
