Forebrain/Diencephalon

Question 1

What are the objectives of this lecture?

Answer 1

1. Identify the major structures of the telencephalon and diencephalon on coronal and sagittal preparations: thalamus, hypothalamus, components of the basal ganglia, internal capsule, neocortex, hippocampus.
2. Prepare a table showing for each of the following systems, the name of the associated thalamic nucleus and the ultimate cortical target of the system: visual, auditory, somatosensory for the face, somatosensory for the body, taste, hippocampal limbic and amygdalar.
3. Identify the following limbs of the internal capsule: anterior, posterior, retrolenticular and sublenticular limbs and list the contents of these four regions.
4. List the functional significance of each of the following Brodmann’s areas and identify the associated thalamic relay nucleus: 1-3, 4, 17, and 41.
5. Identify the following structures in coronal and horizontal sections through the brain: 1) thalamic nuclei: anterior nuc., lateral and medial geniculate nuclei, VA-VL, pulvinar, VPL-VPM, centromedial, dorsomedial (DM), and 2) parts of the internal capsule: anterior, posterior, retrolenticular, and sublenticular limbs.
