Flashcards in Limbic System Deck (21):
1

limbic system functions in ...

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

2

inputs into the hippocampus

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

3

what are the outputs to the hippocampus

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

4

anterograde amnesia

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

5

alzheimer's disease

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

6

inputs to the amygdala

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

7

outputs of the amygdala

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

8

sensation of smell reaches the cortical areas without going through the

thalamsu

9

olfactory input reaches the _______and __________ and therefore smell, scent is associated with the memories as well.

amygdala and hippocampus

10

the ________-is known to attach emotional significance to sensory input

amygdala

11

agnosia

visual tactile and auidotyr

12

hyperorality

examining objects excessively by mouth

13

hypermetamorphosis

intensively exploring the immediate environment

14

placidity

no fear or ange

15

hyperphagia

eating objects that aren't food

16

Kluver-Bucy Syndrome

agnosia, hyperorality, hypermetamorphosis, placidity, hyperphagia, hypersexuality

17

outputs of the septal nuclei

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

18

Korsakoff syndrome

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

19

confabulation

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

20

wernicke-korsakoff syndrome

korsakoff plus ataxia (cerebellar damage)

21

akinetic mutism

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