Clinically, there are only a few conditions related to thalamic damage and dysfunction. This structure contains the subthalamic nucleus of Luys, the zone of uncertainty, the prerrupal field of Forel, the pale globe, and the compact dorsal, and the ventral reticular portions of the substantia nigra (black substance). Likewise, and thanks to its connection to the limbic system, it participates in certain emotional processes. 6. Brain anatomy Cerebellum Cerebellum n n n The. In cerebrum between the division of two hemispheres there is a division known as diencephalon. Controls motor function.

The thalamus is composed of different nuclei that each serve a unique role, ranging from relaying sensory and motor signals, as well as regulation of consciousness and alertness. Its most prominent structure is the subthalamic nucleus. The epithalamus is the most dorsal and posterior part of the diencephalon. The subthalamus is the most ventral part of the diencephalon. Structure: it is composed of the subthalamic nucleus of Luys, the uncertain zone, the preruptive field of Forel, the globus pallidus and the compact dorsal and ventral reticular portions of the substantia nigra; Functions: it participates in the regulation of movements and is linked to the production of dopamine and therefore to the brain's reward system; Hypothalamus. Corpus Striatum- (The largest subcortical brain structure of the basal ganglia is the striatum with a volume of approximately 10 cm).It is a heterogeneous structure that receives afferents from several cortical and subcortical structures and projects to various basal ganglia nuclei.
