Document Summary
Identify main structures that comprise the bg: compare the direct & indirect striopallidal pathways of the bg. Basal ganglia function: motor coordinate speed & strength of mvmts, cognition, learning, emotions. Location and shape of the lateral ventricles in the cerebrum. Coronal section at an anterior level of the basal ganglia. Summary anatomical names of the basal ganglia. Summary anatomical locations of the basal ganglia 1: basal ganglia involved in a wide variety of functions **motor control**, cognition, learning & emotions. Cns centers that participate in motor control: the command of skeletal muscle. Ideomotor area: premotor cortex, primary motor cortex, basal ganglia, cerebellum, spinal reflexes. Basal ganglia connections: direct striopallidal pathway results in activation of the cerebral cortex, dopamine input from substantia nigra modulates both pathways. Indirect striopallidal loop includes the subthalamic nucleus results in activation of the cortex. Summary motor control pathways of the bg: already learned about the premotor and primary motor cortex.
