Flashcards in Review from TDN -Bales Deck (21):
What supplies the thalamus and where do they come from?
anterior choroidal a (MCA)
posterior choroidal A (PCA
both wrap around the thalamus
What is a stroke to the thalamus?
What results from an LGN lesion?
Where is histamine made?
TMN (tuberomammilary nuc)
Where in brainstem can you find isodendritic cells?
lateral reticular formation
Where does NE get produced in the brain?
What will happen with breathing with a lower medulla lesion?
Ondines curse. can only voluntarily breathe (can't sleep)
what's the order or Papexzcircuit?
hippocampus → hypothalamus → thalamus → cortex (cingulate gyrus) → hippocampus
Why is septal nucleus important?
connections include cingulate gyrus, habenula, hypothalamus, hippocampus, and amygdala
What lobe is the parahippocampal gyrus in?
Where does the hippocampal formation transition from 6 --> 3 layers?
What is the first thing damaged in hypoxic states? What will be damaged?
Sommer's sector (CA1 in the hippocampus)
Where does the blood anterior choroidal a of the hippocampus come off?
ICA (not MCA like the thalamus)
Bilateral amygdala lesions
loss of fear, compulsive oral exploratory behavior, and hypersexuality.
anterior medial temporal lobe lesion
stuck in the past
In the cortex, what are the granular cells?
How does the thalamus talk to the cortex?
layer 4 of the cortex
Which sense will not have a layer 6 of the cortex?
What is prosopagnosia? Where would a lesion cause this?
inability to recognize faces
inferior temporal lobe (BA37)
Lesion of the frontal eye fields? Stimulation?
lesion: look towards
stimulate--> look away
