Parasubiculum 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 parasubiculum is the most dorsal region of the parahippocampal [cortex](/brain-regions/cortex), forming a critical interface between the hippocampal formation and the [entorhinal cortex](/brain-regions/entorhinal-cortex). It contains specialized neuronal populations including grid cells, border cells, and head direction cells that are essential for spatial navigation and memory. [@boccara2015]
