A detailed diagram shows the striatum within a cross-section of the human brain.

Definition

Noun 1. A region of the brain: The striatum is a major component of the basal ganglia, a group of structures in the brain involved in movement, learning, and reward. It is characterized by its striped appearance of alternating white and grey matter. 2. A specific anatomical structure: It is located in the forebrain, in front of the thalamus within each cerebral hemisphere. The striatum is primarily composed of two nuclei: the caudate nucleus and the lenticular nucleus (which includes the putamen and globus pallidus).

Usage Examples

• Noun:
  • Damage to the striatum can result in movement disorders like Parkinson's disease.
  • The striatum plays a crucial role in processing rewards and motivating behavior.
  • Researchers are studying how dopamine affects activity in the striatum.*

Advanced Usage

• "Ventral striatum": Refers to a lower part of the striatum, which includes the nucleus accumbens and is heavily associated with reward, pleasure, and addiction.
  • The ventral striatum is activated when we experience something pleasurable.
• "Dorsal striatum": Refers to an upper part of the striatum, more associated with motor control and habit formation.
  • Procedural learning and the development of habits depend on the dorsal striatum.*

Variants and Related Words

• Striatal (adjective): Pertaining to the striatum.

• Neostriatum (noun): A term sometimes used synonymously with the striatum, or more specifically to refer to the caudate nucleus and putamen together.

Synonyms

• Striate body (noun): A direct descriptive synonym.
• Basal ganglia component (noun phrase): A functional classification. (Note: The striatum is a part of the basal ganglia, not synonymous with the entire structure.)
