Psyc 311 Exam Ii

Front 1

External Capsule

Back 1

WHITE. Carries cholinergic axons from the basal forebrain to the cortex.

Front 2

Internal Capsule

Back 2

WHITE. Carries axons from the cortex to the brain stem. Also, carries axons from the thalamus to the cortex.

Front 3

Corona Radiata

Back 3

WHITE. Contains the axons that project from the thalamus to various regions of the cortex. Continuation of the internal capsule.

Front 4

Corpus Callosum

Back 4

WHITE. Connects the two hemispheres.

Front 5

Lateral Ventricle

Back 5

OTHER. Cavities lateral to the corpus callosum.

Front 6

Putamen

Back 6

GREY. 2 Major input areas of the Basal Ganglia. Receives input from the cortex, thalamus, and brain stem. Outputs to the globus pallidus and substantia nigra.

Front 7

Caudate

Back 7

GREY. Most superior part of the basal ganglia.

Front 8

Septum Pallucidum

Back 8

OTHER. The thin membrane that divides the lateral ventricles

Front 9

Anterior Commisure

Back 9

WHITE. Connects the two hemispheres. Connects the olfactory areas and medial temporal lobe.

Front 10

Optic Chiasm

Back 10

WHITE. Intersection of the optic nerve from each eye.

Front 11

Cingulate Gyrus

Back 11

OTHER. Part of the limbic system.

Front 12

Cingulate Sulcus

Back 12

OTHER. Forms the superior boundary of the cingulate gyrus.

Front 13

Cingulum

Back 13

WHITE. Allows communication between the limbic system and the frontal lobe.

Front 14

Septal Nucleus

Back 14

GREY. Has acetylcholine connections with the limbic system. Has been associated with reward and positive reinforcement.

Front 15

Globus Pallidus

Back 15

GREY. Outputs from the Basal Ganglia, projects to the motor areas of the cortex and midbrain.

Front 16

Fornix

Back 16

WHITE. Connects with the thalamus and hippocampus.

Front 17

Descending tract of the Fornix

Back 17

WHITE. Connects the hippocampus with the septal nuclei and mammillary bodies

Front 18

III Ventricle

Back 18

OTHER. Connects the lateral ventricle with the IV ventricle via cerebral aqueduct

Front 19

Amygdala

Back 19

GREY. Linked to fear conditioning, emotions, and aggression.

Front 20

Thalamus

Back 20

GREY. Principle relay station for incoming sensory information (except olfactory).

Front 21

Hypothalamus

Back 21

GREY. Connected to the pituitary gland, which releases hormones into the blood. Hypothalamus is the center of the endocrine system and controls hunger, thirst, circadian rhythms, and reproductive cycles.

Front 22

Mammillothalamic Tract

Back 22

WHITE. Part of the limbic system. Connects the mammillary bodies with the thalamus.

Front 23

Optic Tract

Back 23

WHITE. Axons that project to the Lateral Geniculate Nucleus (LGN).

Front 24

Hippocampus

Back 24

GREY. Part of the limbic system. Involved in spatial navigation and learning and memory.

Front 25

Mammillary Bodies

Back 25

GREY. Part of the limbic system. Associated with Memory. Act as relay nuclei from the amygdala and hippocampus to the thalamus via the mammillothalamic tract.

Front 26

Posterior Commisure

Back 26

WHITE. Required for pupillary light reflex.

Front 27

Lateral Geniculate Nucleus

Back 27

GREY. Processes incoming visual information before processing in the cortex.

Front 28

Medial Geniculate Nucleus

Back 28

GREY. Processes incoming auditory information before being processed in the cortex.

Front 29

Pineal Gland

Back 29

GREY. Plays a role in the hormonal regulation of circadian rhythms.

Front 30

Substantia Nigra

Back 30

GREY. Part of the basal ganglia. Provides dopaminergic output to the motor areas of the cortex and midbrain. Implicated in Parkinson's.

Front 31

Cerebral Aqueduct

Back 31

OTHER. Connects the IV ventricle with the III ventricle.

Front 32

Optic Radiations

Back 32

WHITE. Carries visual information from the Lateral Geniculate Nucleus to the primary visual cortex.

Front 33

Central Gray (Periacqueductal Gray)

Back 33

Grey. Surrounds the cerebral aqueduct.

Front 34

Inferior Colliculus

Back 34

GREY. Between cerebellum and cerebral hemispheres.

Front 35

Superior Colliculus

Back 35

GREY. Coordinates incoming sensory input to make a map of the world.

Front 36

Reticular Formation

Back 36

GREY. Involved in wake/sleep cycles and filtering out irrelevant background stimuli.

Front 37

Cerebellar Peduncles

Back 37

WHITE. The primary input fibers of the cerebellum.
