Dorsal striatum

Dorsal Striatum

The Dorsal Striatum (pronunciation: /ˈdɔːrsəl straɪˈætəm/) is a significant component of the Basal Ganglia, a group of nuclei in the brain associated with control of voluntary motor movements, procedural learning, habit learning, eye movements, cognition, and emotion.

Etymology

The term "Dorsal Striatum" is derived from the Latin words 'dorsum' meaning 'back' and 'striatum' meaning 'striped'. The term 'striatum' is used due to the striped appearance of the structure in brain sections, while 'dorsal' is used to differentiate this region from the Ventral Striatum.

Structure

The Dorsal Striatum is divided into two main structures: the Caudate Nucleus and the Putamen. These structures are separated by a white matter tract called the Internal Capsule. The Dorsal Striatum receives input from various areas of the Cerebral Cortex, including the Motor Cortex, Somatosensory Cortex, and Prefrontal Cortex.

Function

The Dorsal Striatum plays a crucial role in the control of movement, as well as the learning and execution of automatic, habitual behaviors. It is also involved in the reward system and the development of compulsive behaviors and addiction.
