thalamic syndrome
|
caused by damage to Ventral Posterior aspect of the thalamus.
Symptoms: -contralateral loss of propricoception, temp, pain, and touch. -when threshold is reached, the sensation is exegerrated, painful,perverted and disagreeable. (e.g. prick of pin feeels like severe burning sensation, or music that used to be pleasent is now disagreeable). -sometimes spontaneous pain, with forced laughter and crying. |
|
|
lesions placed surgically in intralaminar nuclei to control what?
|
inatractable pain
|
|
|
each area of the cerebral cortex has projections with the thalamus except what two places?
|
the olfactory and reticular nucleus
|
|
|
what is the function of the reticular nucleus?
|
to modulate signal exchange between thalamic nuclei and the cerebral cortex.
|
|
|
what are the inputs, outputs, and function of the intralaminar nuclei?
|
input:reticular formation
output:cerebral cortex function:arousal, consciousness |
|
|
what nuclei compose the ventral nuclear group? what their inputs, outputs, and functions?
|
Ventral Nuclear group:
LG MG VPM VPL Ventral lateral (VLP and VLA) and ventral anterior (VA) Postrior nuclear group medial geniculate - music lateral geniculate - visual field Ventral lateral (VLP and VLA) and ventral anterior (VA) - motor pathways Ventral posterior lateral - somatic sensation from body ventral posterial medial - somatic sensation from head Ventral posterior anterior |
|
|
what nuclei compose the lateral nuclear group? what their inputs, outputs, and functions?
what nuclei compose the lateral nuclear group? what their inputs, outputs, and functions? |
lateral nuclear group nuclei:
LD, LP, pulivnar Medial group nuclei: MD, MV, anterior nucleus Lateral and medial nuclei are all involved in the limbic system. |
|
|
anterior nucleus is part of the medial group. What are its inputs, outputs, and what overall function it participates in?
|
input:mamillary bodies
ouput:cingulate gyrus function: memory |
