Limbic System

Front 1

What is the critical role of the hippocampus?

Back 1

functions related to memory
--connects indirectly to large areas of cortex
-lesions of hippocampus or fn'ally related areas affect consolidation of short-term memory into long-term memory

Front 2

what is critical role of amygdala?

Back 2

emotions and overt expression
-establish emotional significance of stimuli, mediate internal/external emotional expression.
-lesions: alter ability to recognize emotionally sign sensory stimuli and alter expression of emotional states.

Front 3

what is role of nucleus accumbens?

Back 3

rewarding behaviors.
--addiction: nucleus accumbens and dopaminergic inputs

Front 4

Fn of Papez circuit?

Back 4

consolidate short term memories into long-term.

form relations among multiple elements of a memory
---memory in context, memory of facts/events (declarative)
---spatial memory

Front 5

Flow of information in Papez circuitry...begins in the?

Back 5

cingulate cortex --receives inputs from broad areas of cerebral cortex (pre-frontal, pre-motor, sensory association area)and from anterior nucleus. major conduit for HIGHLY PROCESSED info (ie visual face recogn) to go to hippocampus

Front 6

the cingulate cortex projects via the cingulum to the?

Back 6

entorhinal cortex: which also receives input from widespread areas of cortex (olfactory)

Front 7

entorhinal cortex projects to the ?

Back 7

hippocampal formation: forms associations among inputs, primarily from cingulate or entorhinal cortex, thru process of long-term potentiation.

Front 8

hippocampal formation projects to the ? via the fornix

Back 8

mammillary body (of hypothalamus)

Front 9

mammillary neurons project via mammillothalamic tract to the

Back 9

anterior nucleus of thalamus. gateway to cingulate cortex

Front 10

anterior nuc of thalamus projects to?

Back 10

cingulate cortex: provides output to other areas of cortex

Front 11

learning and memory depend on other str

septal nuclei

Back 11

input: hippocampal formation via fornix, amygdala, and ventral tegmental area of midbrain (dopaminergic)

output: hippocampal formation, limbic association cortex, medial dorsoal thalamic nucleus, habenula via stria medullaris

Front 12

Alzheimer's disease involves degeneration of cholinergic neurons in which two nuclei?

Back 12

basal nucleus of meynert and septal nuclei?

Front 13

habenula

Back 13

can alter sleep-wake cycle

Front 14

lesions of hippocampus diminish consolidation of short-term memory to long-term memory

Back 14

ischemia

korsakoff's syndrome -chronic alcoholism
---thiamine deficiency and damages diencephalic str

Front 15

corticomedial nuclei

Back 15

input: olf bulb
output: ventromedial nucleus

fn: mediates olfactory-based reg of feeding behavior

Front 16

basolateral nuclei

Back 16

fn; mediate cognitive / conscious features of emotions; combine sensory inputs to establish emotional sign of sensory stimuli

Front 17

central nucleus of amygdala :

Back 17

one that projects to that list of shit

Front 18

Kluver-Bucy syndrome

Back 18

bilateral temporal lobe lesions that inc amygdala
-reduce monkey ability to assess signficiance ofsensory input
--overattentiveness, hyperorality, psychic blindness (see but do not understand), disorder eating (food vs non-food), sexual hyperactivity

Front 19

urbach-wiethe disease

Back 19

bilateral caclfication of anterior-medial temporal lobes

cannot recognize fear in faces
