Limbic System

Question 1

limbic system functions in …

Answer 1

emotion, motivation, memory, learning. it also has neuroendocrine functions and autonomic activities

Question 2

inputs into the hippocampus

Answer 2

septal nuclei, amygdyla, hypothalamus, cingulate cortex, and cortex (frontal,temporal lobe)

Question 3

what are the outputs to the hippocampus

Answer 3

cingulate cortex, anterior thalamus, stria terminalis, ventromedial nucleus, amygdala, mamillary body, cortex (entorhinal, tempora), septal nuclei, nucleus accumbens, medial frontal cortex

Question 4

anterograde amnesia

Answer 4

injury to the hippocampus results in loss of short term memory. The patients cannot remember anything that occured longer than a few minunutes before and memories in the distant past and the intelligence remain intact

Question 5

alzheimer’s disease

Answer 5

intracellular neurofibrillary tangles and extracellular amyloid deposits are the hallmark, subiculum, entorhinal crotex are the first sites where abnormlaities will appear

Question 6

inputs to the amygdala

Answer 6

olfactory, septal nuclei, hypothalamus, bed nucleus of stria terminalis, cortex (temporal, prefrontal, cingulate), hippocampus, and brainstem nuclei

Question 7

outputs of the amygdala

Answer 7

septal nuclei, nuclues accundens, hypothalamus, hippocampus, cortex, and brainsstem nuclei

Question 17

outputs of the septal nuclei

Answer 17

cingulate cortex, septa nuclei, amygdala, hippocampus, ventral tegmental area

Question 18

Korsakoff syndrome

Answer 18

prolonged thiamine deficiency typically in chronic alcohols, confabulation occurs, mammilary bodies, dorsomedial nucleus of thalamus, fornix, and the hippocampal formation are lesionsed

Question 19

confabulation

Answer 19

stringing together fragments of memory form different events to create an artificial memory of an event that never occured

Question 20

wernicke-korsakoff syndrome

Answer 20

korsakoff plus ataxia (cerebellar damage)

Question 21

akinetic mutism

Answer 21

bilateral lesions of the anterior part of the cingulate gyrus, diinished emotional respoonse, patient is immobile, mute and unresponsive, memory deficits are common
