striate body
A detailed anatomical diagram shows the striate body within a cross-section of the human brain.
Noun: * In neuroanatomy, the striate body is a major component of the basal ganglia, a group of subcortical nuclei in the forebrain. It is characterized by its striped appearance (due to bands of nerve fibers) and is primarily involved in the regulation of movement, procedural learning, and aspects of cognition and emotion.
The term "striate body" is a technical, anatomical term used almost exclusively in medical, biological, and neuroscience contexts. It refers to a specific brain structure. * The striate body is a key node in the brain's motor circuits. * Degeneration of neurons in the striate body is associated with movement disorders like Huntington's disease. * Researchers studied the role of the striate body in habit formation.
- Functional Context: The striate body is often discussed in terms of its input and output pathways. It receives signals from the cerebral cortex and sends processed signals back to the cortex via the thalamus, forming a loop critical for motor control.
- The striate body integrates cortical information before relaying it to other basal ganglia structures.
- Corpus Striatum: This is the direct Latin-derived synonym for "striate body" and is used interchangeably in scientific literature.
- Striatum: A more common, abbreviated term for the same structure. "Striatum" is often preferred in modern neuroscience.
- Neostriatum: A more specific term that refers to the caudate nucleus and putamen together, which are parts of the striate body.
- Basal Ganglia: The larger group of nuclei to which the striate body belongs.
The term "striate body" has a single, specific meaning in anatomy and does not have other common definitions.
- Corpus Striatum
- Striatum
- Caudate Nucleus: A C-shaped structure, part of the striate body.
- Lenticular Nucleus (or Lentiform Nucleus): Comprising the putamen and globus pallidus; the putamen is part of the striate body.
- Putamen: The larger, outer part of the lenticular nucleus and a primary component of the striate body.
- Basal Ganglia: The functional group containing the striate body.

- a striped mass of white and grey matter located in front of the thalamus in each cerebral hemisphere; consists of the caudate nucleus and the lenticular nucleus
