Answer 4

gray matter

Question 5

Basal Ganglia: putamen

Answer 5

striations (striped)

Question 6

Basal Ganglia: globus pallidus

Answer 6

white matter, helps inhibit sub thalamic nuclei

Question 7

Corona Radiata

Answer 7

subset of corpus callous, white matter, “crown” that radiates through cortex

Question 8

PMC/SMC

Answer 8

pre motor, supplementary motor

Question 9

Broca’s area

Answer 9

production of speech

Question 10

Wernicke’s area

Answer 10

comprehension of speech

Question 11

Thalamus

Answer 11

declarative memories, sensory processing, projects to amygdala.

Question 12

Subthalamic Nuclei

Answer 12

excites PMC/SMC

Question 13

Parkinsons Disease

Answer 13

when substantia nigra is damaged so inhibition of sub thalamic nuclei is weaker

Question 14

Cingulum

Answer 14

runs through cingulate, white matter, projects to entorhinal cortex.

Question 15

Papez Circuit

Answer 15

circuit that is key for encoding new declarative memories

Question 16

Anterior Cingulate

Answer 16

kickstart the encoding of papez circuit, shocking things you remember more

Question 17

Entorhinal Cortex

Answer 17

gateway to hippocampus

Question 18

Hippocampus

Answer 18

encodes memories, but does NOT store or retrieve memories

Question 19

Mammillary Bodies

Answer 19

Projects to anterior thalamus, is damaged Korsakoff’s syndrome

Question 20

Korsakoff’s syndrome

Answer 20

usually caused by alcoholism, affects memory

Question 21

Mammillothalamic Tract

Answer 21

tract that projects from mamm. to thalamus. Projects to anterior thalamus.

Question 22

dlPFC

Answer 22

actively retrieves memories (thinking about what gma looks like). retrieves declarative memories (working memory).

Question 23

Amygdala

Answer 23

next to hippocampus, tucked into temporal lobe. “hub” for negative emotions, cranks UP HPA.

Question 24

This connects 2 amygdale

Answer 24

Anterior commissure

Question 25

The 4 places amygdala projects to:

Answer 25

HPA axis, sympathetic ns, locus coeruleus, periaqueductal grey

Question 26

Suprachiasmatic N.

Answer 26

uses light cues (zeitgebers), projects to pineal, above optic chiasm.

Question 27

Fornix

Answer 27

floor of corpus callosum, connects hippocampus to mammillary

Question 28

Cerebral Aqueduct

Answer 28

connects 3rd & 4th ventricles, under tectum.

Question 29

Habenula

Answer 29

Tear shaped thing, "makes party look less fun".

Question 30

Dorsolateral PFC

Answer 30

working memory, help prevent mind wandering

Question 31

Ventromedial PFC

Answer 31

sense of self, inhibit for future self

Question 32

Orbitofrontal PFC

Answer 32

updating reward values (after eating a lot of a food, don't want it no more)

Question 33

Reticular Formation

Answer 33

VTA (produces dopamine), substantia nigra (dopamine), locus coeruleus (norepinephrine), raphe nuclei (serotonin)(projects everywhere)

Question 34

Central NS

Answer 34

brain & spinal cord

Question 35

Hypothalamus

Answer 35

regulates the 4 F's (fight, flight, feeding, fucking)

Question 36

Pineal Gland

Answer 36

in front of tectum, releases melatonin

Question 37

Anterior Commissure

Answer 37

little dot in front of thalamus

Question 38

Posterior Commissure

Answer 38

connects 2 superior colliculi, in between pineal & thalamus
