Flashcards in Review from TDN -Bales Deck (21):
1

What supplies the thalamus and where do they come from?

anterior choroidal a (MCA)

posterior choroidal A (PCA

both wrap around the thalamus

2

What is a stroke to the thalamus?

lacunar stroke

3

What results from an LGN lesion?

homonymous hemianopia

4

Where is histamine made?

TMN (tuberomammilary nuc)

5

Where in brainstem can you find isodendritic cells?

lateral reticular formation

6

Where does NE get produced in the brain?

Locus ceruleus

7

What will happen with breathing with a lower medulla lesion?

Ondines curse. can only voluntarily breathe (can't sleep)

8

what's the order or Papexzcircuit?

hippocampus → hypothalamus → thalamus → cortex (cingulate gyrus) → hippocampus

9

Why is septal nucleus important?

connections include cingulate gyrus, habenula, hypothalamus, hippocampus, and amygdala

10

What lobe is the parahippocampal gyrus in?

medial temporal

11

Where does the hippocampal formation transition from 6 --> 3 layers?

subiculum

12

What is the first thing damaged in hypoxic states? What will be damaged?

Sommer's sector (CA1 in the hippocampus)

memory

13

Where does the blood anterior choroidal a of the hippocampus come off?

ICA (not MCA like the thalamus)

14

Bilateral amygdala lesions

Kluver-Bucy syndrome

loss of fear, compulsive oral exploratory behavior, and hypersexuality.

15

anterior medial temporal lobe lesion

stuck in the past

16

In the cortex, what are the granular cells?

afferent

17

How does the thalamus talk to the cortex?

layer 4 of the cortex

18

Which sense will not have a layer 6 of the cortex?

olfactory

19

What is prosopagnosia? Where would a lesion cause this?

inability to recognize faces

inferior temporal lobe (BA37)

20

Lesion of the frontal eye fields? Stimulation?

lesion: look towards

stimulate--> look away

21

A lesion where would cause astereognosis?

right parietal

superior-->left sided hemineglect
