VISIBLE BRAIN MOVIE: INS & OUTS OF THE CNS ABOVE THE
labels deep structures seen beneath the cerebral cortical mantle.
• Basal Ganglia are
deep gray matter nuclei important in cognitive and sensori-motor behaviors and include: Striatum = Caudate Nucleus + Putamen, Globus Pallidus, Substantia Nigra and Subthalamic Nucleus.
• Thalamus is a gray matter structure that serves as the gateway to the cerebral cortex. It includes a number of separate nuclei that relate to sensory, motor, limbic and cognitive functions.
• Internal Capsule is a white matter structure that contains axons originating from pyramidal cells in the cerebral cortex that travel to brainstem and spinal cord structures plus thalamo-cortical & corticothalamic axons that link the thalamus to the cerebral cortex.
• Amygdala is a gray matter nucleus involved in limbic functions
including reactions to highly charged
affective stimuli, memories, or events.
• Red Nucleus is a midbrain
that contributes to
our control of dexterous limb movements.
