Q

Central nucleus

A

Q

Basolateral nucleus

A

major input of the amygdala
largest, most differntiated cells
Pyramidal/ Glutamate

input is from the sensory cortex, thalamus)

Main output is to the central nucleus
also has output to the enterohinal cortex and subiculum of the hippocampus

**important for learning fear (integrates emotions and memories)

Q

Tri-synaptic circuit of the hippocampus

A

perforant pathway
ERC > DG > CA3 > CA1
CA 3 and CA1 have commissure fibers to the opposite hippocampus and the septate nucleus

input from CA-1

17
Q

neuro dz w/ calcification of neural tissue

A

Ubech-Weith disease

18
Q

What is the gyrus involved w/ the conduction aphasia?

A

supramarginal gyrus

19
Q

Transcortical sensory aphasia - lesion is where? w/ another symptom?

A

border zone between the middle cerebral and the posterior cerebellar arteries
also may have severe HOTN

20
Q

Gerstmann syndrome?

A

Anomic aphasia - anomia, agraphia alexia, right-side disorientation

left angular gyrus lesion

21
Q

Alexia w/o agraphia

A

Ability to write but cannot read
Lesion is in the left medial occipital and medial temporal lobe involving the splenium of the corpus callosum
Left posterior cerebral artery occlusion

22
Q

Can occur if you correct the hyponatremia too quickly

A

Central Pontine Myelinolysis
