1
Q

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

A

Thalamus

2
Q

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)

A

Thalamus

3
Q

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

A

Function of the thalamus

4
Q

Thalamus regions

A
Anterior= affective (outward projection of emotion)
medial = arousal (info to and from reticular formation)
lateral = motor
posterior = sensory
5
Q

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

A

Limbic lobe the anterior nucleus

6
Q

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

A

Dorsomedial nucleus (prefrontal lobe)

7
Q

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

A

Ventral anterior nucleus

8
Q

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

A

ventral lateral nucleus

9
Q

relays info to sensory areas of the cortex

A

ventral posterior nucleus

10
Q

subsections of the ventral posterior nucleus

A

VPI, VPM, VPL

11
Q

relay somatosensory info to the cortex

A

VPM, VPL

12
Q

relays vestibular info ot the cortex

A

VPI

13
Q

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

A

Pulvinar nucleus

14
Q

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

A

Lateral geniculate nucleus

15
Q

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

A

medial geniculate nucleus

16
Q

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

A

Intralaminar, centromedian, and midline nuclei

17
Q

internal capsule

A
Anterior= affective
Genu = motor from cortex and internal motor system with basal ganglia and cerebellum
Posterior = motor (from cortex); sensory
18
Q

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

A

Thalamic Pain syndrome
