Question 1

Processing station where info is organized before being transmitted to cerebral cortex

Answer 1

Thalamus

Question 2

receives all sensory inputs except olfactory
Transmission of conscious awareness of pain, touch and temperature
Receives and processes all internal motor systems (basal ganglia, cerebellum)

Answer 2

Thalamus

Question 3

general arousal via reticular conneciton
sensory connection via spinal cord and brain stem
motor connection via basal ganglia and cerebellum
emotional tone/affect via limbic system and prefrontal lobe connections

Answer 3

Function of the thalamus

Question 4

Thalamus regions

Answer 4

Anterior= affective (outward projection of emotion)
medial = arousal (info to and from reticular formation)
lateral = motor
posterior = sensory

Question 5

relays information from subrotical limbic structures to cortical limbic structures (cingulate gyrus) to contribute to emotional tone

Answer 5

Limbic lobe the anterior nucleus

Question 6

Relays info to and from the prefontal lobe, to contribute to judgement and reasoning

Answer 6

Dorsomedial nucleus (prefrontal lobe)

Question 7

relay info from globus pallidus of basal ganglia and cerebellum (secondary) to premotor areas and M1 (secondary) important for motor planning/regulation

Answer 7

Ventral anterior nucleus

Question 8

relays info from cerebellum and globus pallidus of basal ganglia to M1 (primary cb) and premotor areas (primary BG); important for motor output regualtion

Answer 8

ventral lateral nucleus

Question 9

relays info to sensory areas of the cortex

Answer 9

ventral posterior nucleus

Question 10

subsections of the ventral posterior nucleus

Answer 10

VPI, VPM, VPL

Question 11

relay somatosensory info to the cortex

Answer 11

VPM, VPL

Question 12

relays vestibular info ot the cortex

Answer 12

VPI

Question 13

relays info among cortical association cortices, including areas 5/7 and areas 18/19

Answer 13

Pulvinar nucleus

Question 14

relays visual info to primary visual cortex (area 17 of the occipital lobe)

Answer 14

Lateral geniculate nucleus

Question 15

relays auditory info to primary auditory cortex (area 41 of the temporal lobe)

Answer 15

medial geniculate nucleus

Question 16

Nuclei relay arousal info from the reticular system to widespread areas of the brain

Answer 16

Intralaminar, centromedian, and midline nuclei

Question 17

internal capsule

Answer 17

Anterior= affective
Genu = motor from cortex and internal motor system with basal ganglia and cerebellum
Posterior = motor (from cortex); sensory

Question 18

Infarct in VPL
patient experience spontaneous burning pain and other abnormal sensations (dysesthesia)
Response to normal sensory input or spontaneously occurs
Location and intensity of pain varies

Answer 18

Thalamic Pain syndrome
