Ondines curse. can only voluntarily breathe (can’t sleep)
what’s the order or Papexzcircuit?
hippocampus → hypothalamus → thalamus → cortex (cingulate gyrus) → hippocampus

connections include cingulate gyrus, habenula, hypothalamus, hippocampus, and amygdala
What lobe is the parahippocampal gyrus in?
medial temporal
Where does the hippocampal formation transition from 6 –> 3 layers?
subiculum
What is the first thing damaged in hypoxic states? What will be damaged?
Sommer’s sector (CA1 in the hippocampus)
memory
Where does the blood anterior choroidal a of the hippocampus come off?
ICA (not MCA like the thalamus)
Bilateral amygdala lesions
Kluver-Bucy syndrome
