complete the diagram by which the major motor centers influence the motor cortices | wide areas of cerebral cortex, substantia nigra, thalamic nuclei (all 3) to neostratium to paleostratium to ventral lateral nuclei and ventral anterior nuclei (also going to VLN and VAN is globus emboliform and dentate) VLN to Areas 4 & 6 to Lower Motor N |
a person has a vascular lesion which gives signs and symptoms of both basal nuclear and and pontocerebellar dysfunctions. give the most likely location of the lesion | anterior limb of internal capsule |
a person has vascular lesion which interrupts the left temporal loop fibers. Darken the expected blind visual areas | darken upper right quarter of both circles |
what motor deficits is likely with an interruption of fibers in the genu of the left internal capsule? | Deviation of protruded tongue; inability to smile on the right |
name the motor condition described: characterized by truncal ataxia and nystagmus | flocculonodular syndrome |
