Centromedian Thalamic Nucleus (Cm) Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The centromedian nucleus (CM) is a prominent midline thalamic nucleus belonging to the intralaminar nuclear group. CM neurons play critical roles in arousal, attention, and sensorimotor integration, and are implicated in various neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, and frontotemporal dementia.
