|
|
Ventral Lateral Nucleus (VL)/ Ventral Anterior (VA)
|
I:Basal ganglia (GP, Substantia Nigra); 2) Cerebellum
O: Motor Cortex F:Faciliatates movement- muscle control You need this to GO to VA |
|
|
Pulvinar
|
I: Superior colliculus
O: Parietal lobe F: Visual association, Behavioral response to visual stimuli That dude just kissed my girl, and now my pulvinar is making me pulverize his face into pulp. |
|
|
Mediodorsal Nucleus (MD)
|
I: !Frontal Lobe 2) limbic system
O: Frontal Cortex F: Personality & executive function emotional behavior toward relavant visual stimuli I really want to pound this guys face, but the MD in me tells me maybe I shouldn't |
|
|
Anterior Nucleus
|
I: Limbic System (hippocampus & amygdala)
O: Cingulate gyrus F: memory formation; emotion, short term memories Gosh, im really gunna wish my AN is working right now when i take this test... OR, to be AN Einstein, you need a good AN. |
|
|
VPL/ VPM deficit
|
contralateral loss
May be more noticable in the face, hand, foot- rather than trunk Sensory only, not motor |
|
|
VA/VL deficit
|
Parkinsonian tremor, gait
cannot GO efficiently |

Which of the following statements is FALSE concerning thalamic syndrome:
A. the pain involved may be very disagreeable and may become intractable to analgesics. B. the syndrome usually results from a lesion that is vascular in origin. C. the symptoms of the syndrome vary according to the location and extent of the lesion. D. the threshold for somatic sensory stimuli is usually raised on the same side of the body as the lesion. E. blockage of the posterior cerebral or its thalamic branches can cause the thalamic syndrome. |
FALSE: The threshold for sensory stimuli is raised
