What is the set of 3 C shaped structures embeded in each other to make up the limbic system?
|
Limbic lobe, intralimbic gyrus, inner arc (fronix)
|
|
What are the inputs of the hippocampus?
|
Cingulate cortex, septal nuclei, hypothalamus, amygdala, cortex (frontal, temporal)
|
|
What are the outputs of the hippocampus?
|
Cingulate cortex, septal nuclei, amygdala, cortex 9enthorhinal, temporal), anterior thalamus, bed nucleus of stria terminalis, Ventromedial nucleus
|
|
What happens with damage to the hippocampus?
|
Anterograd amnesia
|
|
What are location that NFT and extracellular amyloids deposit in alzheimers occur?
|
Subiculum, entorhinal cortex-> thus affecting memory
|
|
What is the damage caused by reduced B1 absorption?
|
Korsakoff syndrome = Alcoholics -> ↓ B1 (thiamine intake) -> mamillary bodies, dorsomedial nucleus, fornix, and hippocampal formation are lesioned -> confabulation occurs -> makes up stories that have never occurred.
|
|
What happens in bilateral lesion of the cingulate gyrus?
|
Akinetic mutism = ↓ emotional response, immobile, mute, unresponsive -> memory deficits = common
|
|
What is the circuit of papez?
|
Fornix = major output of hippocampus -> mammilary body -> mamillothalamic tract -> anterior thalamus -> thalamocortical fibers -> cingulate cortex -> cingulum -> hippocampus (makes closed circuit)
|
|
What is the pathway that connects amydala with hypothalamus in septal region
|
Ventral amygdalofugal pathway
|
|
What is the pathway that connects amygdala/hypothalamus to the brainstem?
|
Medial forebrain bundle
|
|
What is the pathway that connects the hippocampus to he septal nuclei?
|
Stria terminalis
|
|
What is the pathway that connects the septal nuclei to habenular nuclei?
|
Stria medularis
|
