Back 10

behavioral motivation.

Front 11

The amygdala has two primary nuclear groups:
1. _group- has primary connections with the olfactory bulb
2. _ has no direct input from olfactory area, but connects with a broad range of areas

Back 11

Corticomedial

basolateral group

Front 12

In addition to olfaction, the corticomedial group is associated with _ functions.

Back 12

Primitive functions, such as reproduction, feeding, and survival

Front 13

The coticomedial group sends connections primarily via the _, which connects the amygdala to the septal area in a long course near the caudate nucleus

Back 13

Stria terminalis,

Amygdala, septal area

Front 15

The basolateral group projections from the amygdaloid complex are primarily through the _ pathway

Back 15

ventral amygdalofugal pathway.

Front 16

The part of the amygdala that is most closely associated with olfactory function is?

Back 16

corticomedial group

Front 17

The substantia innominata gives rise to cholinergic projections that appear to _ in response to an emotional stimulus

Back 17

enhance levels of arousal

Front 18

The major efferent pathway from the septal nuclei is the _

Back 18

stria medullaris thalami.

Front 19

The nucleus accumbens is at the junction of the _ and the _, and is a _ area, associated with the _ system.
It appears to play a role in _

Back 19

caudate nucleus and putamen
Is a dopaminergic area, associated with the central reward pathway.

the amygdala and hippocampus have an abundance of _ centers.
The nucleus accumbens and medial forebrain bundle have an abundance of _ centers.
Stimulation of the septal area has been described as _

Back 20

aversion
gratification
sexual related and pleasurable.

Front 21

The _ and _ have an abundance of aversion centers.
The _ and _ bundle have an abundance of gratification centers.
Stimulation of the _has been described as sexual related and pleasurable.

Back 21

the amygdala and hippocampus

nucleus accumbens and medial forebrain

septal area

Front 22

In _ increased blood flow can be show in the amygdala, mediodorsal nucleus of thalamus, and the orbitofrontal and medial prefrontal cortex.

Back 22

unipolar depression,

Front 23

The _ region of the hippocampus (Sommer’s sector) that is particularly sensitive to anoxia, is a source of hippocampal damage and associated with epilepsy.

Back 23

CA 1

Front 24

__ is one of the most common forms of epilepsy, in this form, seizures usually begin with a complaint of a bad odor associated with a perceived bad taste

Back 24

temporal lobe epilepsy

Front 25

_ is produced by a prolonged thiamine deficiency typically seen in chronic alcoholics.This results in loss of areas of the hippocampus, thalamus (eg. Dorsomedial nucleus), mammillary bodies and the columns of the fornix.

Back 25

Korsakoff’s Psychosis

Front 26

Korsakoff syndrome is characterized by _

Back 26

a loss of short term memory. Cognitive skills may also be impaired.

Patients attempt to string together memory fragments and form a synthetic memory (confabulation)

Front 27

A pre seizure aura which includes a bad taste in the mouth, suggests injury to the...

Back 27

temporal lobe, particularly the uncus

Front 28

_ can result from bilateral lesions of the anterior cingulate gyrus.

Back 28
