  • Front
  • Back

neurons that initiate symp and parasymp responses

hypothalamus, brainstem nuclei

neurons directly in charge of survival related behaviors

hypothalamus, amygdala, septal nuclei

unconscious smell site

parahippocampal gyrus, uncus, amygdala, entorhinal cortex

executive oversight for survival behavior sites

prefrontal, orbitofrontal, and anterior cingulate cortices

contextual learning site

hippocampus, mesiotemporal cortex

conscious smell site

orbitofrontal cortex, dorsomedial thalamus

associated learning site

amygdala, mesiotemporal cortex, stria terminalis

septal area

reward center of brain, nucleus accumbens

hippocampus

contextual learning, archicortex, lesion produces short term memory loss, common site for epileptic seizures to begin

amygdala

learned fear

two pathways out of amygdala

stria terminalis, ventrofugal pathway

hippocampus

learn where good and bad things happen


contextual learning

pathways into amygdala

olfactory tract, sensory relays through thalamus, hippocampus, hypothalamus

2 fear pathways

high road (through cortex)


low road (through sensory thalamus, faster and unconscious)

lateral nucleus of amygdala

where all sensory information arrives

central nucleus of amygdala

initiates fear response

where does the central nucleus project?

lateral hypothalamus (sympathetic)


DMN of Vagus (parasymp)


Peri aquiductal gray (freeze)


reticular formation (startle)


paraventricular nucleus hypo. (Cortisol releasing factor)
