Ventral Striatum
The Ventral Striatum (pronounced: ven-tral stry-a-tum) is a part of the brain that is involved in the reward system and decision-making processes.
Etymology
The term "Ventral Striatum" is derived from Latin, where "ventral" means "belly" and "striatum" refers to a striped appearance.
Anatomy
The Ventral Striatum is located in the basal forebrain and is primarily composed of the Nucleus Accumbens and the Olfactory Tubercle. It is a part 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.
Function
The Ventral Striatum plays a crucial role in the reward system of the brain. It is involved in the processing of rewards, the reinforcement of learning, and the motivation for obtaining rewards. It is also implicated in several psychiatric disorders, including Addiction, Depression, and Schizophrenia.
