Thalamus

Thalamus The structure indicated is the thalamus. The thalamus is the largest of the structures which comprises the diencephalon. The diencephalon consists of: Epithalamus Thalamus Subthalamus Hypothalamus The thalamus essentially acts as a sort of “relay” for the brain, consisting of several nuclei with reciprocal connections to and from the cerebral cortex. It also forms important connections with the hippocampus via the mammillo-thalamic tract, and connections with the spinal cord via the spinothalamic tract which transmits peripheral information regarding pain, temperature and crude touch. The thalamus is therefore important in several functions including, sleep, wakefulness and arousal, consciousness, and sensory/motor …

Globus Pallidus

Globus Pallidus The structure indicated is the globus pallidus. The globus pallidus is a subcortical structure located within the cerebral hemispheres, and is a major component of the basal ganglia. The basal ganglia are a group of subcortical nuclei (collection of neuronal cell bodies located within the CNS) located at the base of the forebrain. The term “basal ganglia” is a misnomer, and the name “basal nuclei” would be more appropriate, since ganglia are collections of neuronal cell bodies located within the peripheral nervous system. The basal ganglia form extensive connections with other areas of the brain and are involved …
