Document Summary
At the inferior olivary nucleus, descending information crosses over. Medium spiny neurons send axons to the globus pallidus. Input structures for the basal ganglia include the striatum and subthalamic nucleus. Output structures for the basal ganglia include the globus pallidus and substantia nigra pars reticulata: networks that connect within the basal ganglia are constantly active, even during rest. In huntington"s disease, the motor cortex is getting overactivity. The subthalamic nucleus receives input from the frontal lobes only. This was observed after a study of individuals with different ailments. Study the locations of these: cerebral falx is a sickle shaped invagination of the lower layer of the dura mater. It helps hold the hemispheres together: cerebellar tentorium helps hold cerebellum in place and forms a tent atop the cerebellum, dura mater is also within the spinal cord. It is continuous with the brain and spinal cord: the bottom of the skull shows indentations of different lobes.
