PRAECOMMISSURE Meaning and
Definition
-
"Præcommissure" is a term derived from Latin that is used to refer to a specific anatomical structure in the central nervous system of mammals, particularly found in rodents. It is a small, thin bundle of nerve fibers that connects two key regions of the brain—the anterior commissure and the precommissural region of the hypothalamus.
The anterior commissure is a prominent white matter tract and is involved in interconnecting the left and right hemispheres of the brain. On the other hand, the precommissural region of the hypothalamus is a part of the brain that is associated with the regulation of various physiological processes, such as body temperature, hunger, thirst, and hormone release.
The præcommissure acts as a conduit or pathway for neural signals between these two important regions, facilitating communication and coordination between them. This connection is essential for the integration and synchronization of various functions mediated by the hypothalamus, as well as for the bilateral transfer of information between the brain hemispheres.
Overall, the præcommissure plays a crucial role in relaying sensory, motor, and regulatory information between the left and right sides of the mammalian brain, contributing to the overall functioning and homeostasis of the organism.
