chandelier cell
A specialized GABAergic interneuron that selectively targets the axon initial segments of pyramidal neurons.
Full Definition
Chandelier cells, also known as axo-axonic cells, are a distinctive type of inhibitory interneuron characterized by their chandelier-like axonal terminals that form synapses specifically onto the axon initial segments of pyramidal neurons. This strategic positioning allows them to powerfully control action potential initiation and neural output. Chandelier cells are implicated in various psychiatric and neurological disorders, including schizophrenia and epilepsy. Their unique morphology and function make them a crucial cell type in neuroscience research and clinical literature.
Usage
Usage note: Often abbreviated as ChC in research literature; distinguish from other interneuron types by their specific axon initial segment targeting.
