Septal Gabaergic 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.
Septal GABAergic neurons are inhibitory neurons in the medial septum and diagonal band of Broca that provide major cholinergic and GABAergic projections to the hippocampus. They play critical roles in hippocampal theta rhythm generation, spatial memory, and navigation. These neurons are significantly affected in Alzheimer's disease and other neurodegenerative conditions. [1]
