General Information
Term neuropil ID (Ontology) FBbt:00005139 (Fly Anatomy)
Definition Multi-cell component structure of the central nervous system consisting largely of neuron projections (tracts and synaptic neuropil domains) and associated glial cells. This corresponds to the part of the CNS that is enclosed by the cortex.[ FlyBase:FBrf0224194 ]
