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
