Areas affected by stress are: amygdala spiny neuron, nacc medium spiny neuron. Monday, january 9, 2017: da neuron in vta and snr, ca3 pyramidal neuron in hippocampus, mpfc pyramidal neuron important for parsing reward = decreased interest if you are stressed out by something. Ca3 neurons have impairment in memory (these are for memory) Dendritic spines conduct aps, and stress can increase dendritic arms or can change function in the pre/post synapses.
