Q

olfactory pathway

A
  1. bulb
  2. tract
  3. medial and lateral stria
  4. medial > anterior commissure to share info with other hemisphere + septal area
  5. lateral > amygdala, piriform lobe, uncus @ temporal lobe

Q

pathways into hippocampus

A
  1. alvear path
  2. perforant path

then thru dentate gyrus before hippocampus proper

receive input from entorhinal cortex

Q

septal area

A

perceptions of pleasure and well being
-inputs from hippocamp and amy complex via stria terminalis
-outputs back to hippo + hypothalamus via medial forebrain bundle + brainstem via medial forebrain

addiction pathway?
