General Information
Term lamina ID (Ontology) FBbt:00003708 (Fly Anatomy)
Definition Lateral-most synaptic neuropil domain of the adult optic lobes, lying just beneath the compound eyes. It is composed of an array of repetitive cartridge-like units, each of which receives axons from specific sets of ommatidia in the compound eyes.[ FlyBase:FBrf0224194 FlyBase:FBrf0231227 ]
Also Known As "LA"
