paleocerebellum
Quick Summary
The paleocerebellum is an embryologically defined part of the cerebellum, specifically the anterior lobe. It plays a role in regulating muscle tone and equilibrium. The cerebellum itself is a crucial section of the brain, located behind the cerebral hemispheres and above the medulla oblongata. It functions to coordinate sensory input with muscular responses, making fine adjustments for balance, posture, and smooth, coordinated movements. The cerebellum is divided into two hemispheres and a midline vermis, with each hemisphere having a gray matter cortex and a white matter core. Injuries to the cerebellum can lead to neuromuscular disturbances like ataxia, tremors, and difficulty with coordinated movements.12

human nervous systemCerebellum…the vestibular system, (2) the paleocerebellum, or anterior lobe, involved with control of muscle tone, and (3) the neocerebellum, known as the posterior lobe. Receiving input from the cerebral hemispheres via the middle cerebellar peduncle, the neocerebellum is the part most concerned with coordination of voluntary motor function.
