Reticular Thalamic Nucleus (Rtn) 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 Reticular Thalamic Nucleus (RTN), also known as the Thalamic Reticular Nucleus, is a thin sheet of GABAergic neurons that surrounds the dorsal thalamus. It serves as the "guardian of the thalamus," playing critical roles in attention, sensory gating, sleep spindles, and thalamocortical rhythm generation. [1]
