General Information
Term larval optic focus ID (Ontology) FBbt:00007131 (Fly Anatomy)
Definition A synaptic neuropil domain of the larval brain formed during larval stages by axons originating from the lobula primordium in the optic lobe and dorso-lateral protocerebrum. These axons form terminal branches lateral to the borders of the centro-posterior lateral and baso-lateral compartments which then become enclosed by a glial sheath, forming this compartment.[ FlyBase:FBrf0155900 ]
Also Known As"LOF"
