Colliculus inferior intrinsic cell

Name: Colliculus inferior intrinsic cell
Description: It is not established that there are "pure" local interneurons of which axons are restricted in the inferior colliculus (IC). However, even after a large injection of retrograde tracer into the medial geniculate body (MGB), a main target of IC projection, most small GABAergic neurons, which lack dense excitatory axosomatic terminals, were not labeled with the tracer. On the other hand, large GABAergic neurons send axons to the MGB.[1]
Synonym(s): small GABAergic (SG) neurons[2]
Has role: Intrinsic neuron role[2]
