PALEOSTRIATUM Meaning and
Definition
-
Paleostriatum is a term used in anatomy and neurobiology to refer to a specific region within the brain. It is part of the basal ganglia, a group of nuclei that play a crucial role in motor functions, cognition, and emotions. The paleostriatum is divided into two main components: the paleostriatum primitivum (also known as the globus pallidus) and the paleostriatum augmentatum (also called the ventral pallidum).
The paleostriatum primitivum is found deep within the brain, close to the thalamus. It is involved in the regulation of movement, acting as an inhibitory control center that sends signals to other areas of the brain to modulate motor behaviors.
In contrast, the paleostriatum augmentatum is positioned ventrally to the paleostriatum primitivum. It is involved in reward processing, motivation, and experiencing pleasure. The paleostriatum augmentatum receives inputs from the limbic system, particularly from regions responsible for emotional responses, and communicates with other brain regions involved in the generation of emotions and behaviors.
The paleostriatum, which is collectively composed of these two divisions, plays a vital role in the modulation of both voluntary and involuntary movements, as well as in the processing of emotions and the reinforcement of motivated behaviors. Through its complex neural connections, the paleostriatum contributes to maintaining proper motor control, emotional regulation, and motivation in the brain.

Etymology of PALEOSTRIATUM
The word "paleostriatum" is derived from the combination of two Latin roots: "paleo" meaning "old" or "ancient", and "striatum" meaning "striped" or "grooved".
In neuroscience, the term "paleostriatum" refers to a part of the basal ganglia, which is an ancient subcortical structure involved in the regulation of movement and other functions. The basal ganglia are composed of several distinct nuclei, and the paleostriatum is an older component of this structure.
The term "paleostriatum" was initially coined by the French anatomist Louis Pierre Gratiolet in the mid-19th century to describe this particular part of the basal ganglia. The word itself reflects the idea that this structure has existed for a long time in evolutionary history and is responsible for certain primitive functions.
