  1. Lab 11 Basal Ganglia System & Blood Supply to Forebrain

  2. transition between head & body = level of interventricular foramen (like level of transition between frontal horn & body of lateral ventricle) 2 (nucleus, be secific) Body of caudate nucleus 1 (nucleus, be specific) Head of caudate nucleus Interventricular foramen 3 (space)

  12. What neurologic signs & symptoms would this patient have? What anatomic structure is affected by the lesion? The patient would develop over the course of several months “unintentional, forceful, flinging movements” of his contralateral limbs, i.e. right upper and lower limbs. These involuntary movements resolved after several weeks of anti-toxoplasmosis treatment . The rim enhancing lesion is in the location of the subthalamic nucleus.

  13. Caudate Body Insular cortex Posterior Limb Int. Capsule Putamen Thalamic Fasciculus Globus pallidus What is the ~location of the: Insular Cortex? Caudate Body? Posterior Limb of IC? Putamen? Thalamic Fasciculus? Globus Palidus?
