Hipp Cells is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
HIPP (Hilus Interneuron Perforant Path-associated) cells are a specialized population of dendrite-targeting interneurons in the dentate gyrus hilus that play critical roles in modulating hippocampal circuit function and memory processing.
