thalamus Flashcards
Ventral lateral
afferent: basal ganglia
efferent: premotor
anterior
afferent: mammillary body (mammillothalamic)
efferent: cingulate gyrus
Ventral anterior
anterior: cerebellar nuclei (superior cerebellar pedurde, cerebellodentatothalamic)
efferent: motor
Ventral Posterior Lateral
VPL
afferent: extremities&trunk (via. spinothalamic, medial lenmiscus)
efferent: primary somatosensory cortex
VPM
Ventral post. Med.
afferent: face, oral, nasal cavity(via trigeminothalamic)
efferent: primary somatosensory certex
Late Geniculate Body
afferent: retina CNII
efferent: primary visual, calcarine sulcus
Med Geniculate Body
afferent: inner ear, superior olive and inferior colliculus of tectum
efferent: primary auditory
Pulvinar
afferent: occipital cortex
efferent: visual area
Lateral dorsal nuc.
LDN
afferent: parietal cortex, cingulate gyrus
efferent: cingulate gyrus
Laternal post. nuc.
afferent: occipital(visual) cortex
efferent: association area of partial cortex
Dorsaomedial nuc
afferent: hypothalamus/prefrontal cortex
efferent: profrontal cortex
intralaminar nuc.
afferent: basal ganglion/ midbrain, frontal lobe, prefrontal cortex
efferent: basal ganglion
alcoholic harms?
dorsomedial/anterior thalamic nuclei: mental status
cortex, vestibular, vermis cerebellum: ataxia
CN III-VI: ocular motor
memory: dorsomedial–>hippocampus, mammary body,
loss of contralateral vib sensation & gait ataxia
increase sensiticity to pain, analgesic not helpful
thalamic pain syndrome
affect the ventral nuclear group
burning ache in contralateral limbs and body
