General Information
Term superior lateral protocerebrum ID (Ontology) FBbt:00007054 (Fly Anatomy)
Definition Lateral synaptic neuropil domain of the adult superior neuropils. It lies behind the anterior optic tubercle, in front of the mushroom body calyx and above the superior clamp and lateral horn. Its boundary with the anterior optic tubercle (AOTU), mushroom body calyx and lateral horn is demarcated by the extent of arborization of visual projection neurons and antennal lobe projection neurons. Boundaries with the superior clamp, anterior and posterior ventro-lateral protocerebrum are defined using clearly distinguishable fiber bundles.[ FlyBase:FBrf0211016 FlyBase:FBrf0212704 FlyBase:FBrf0224194 ]
Also Known As"adult superior lateral protocerebrum" ; "SLP"
CommentBoundaries defined by Ito et al. (2014) (used to define this term) differ slightly from those defined for slpr in Otsuna and Ito, 2006. The anterior superior SLP corresponds to mslpr and the posterior superior SLP to pslpr of Otsuna and Ito (2006). The SLP also corresponds to the lateral part of the dorsolateral protocerebrum (DLP) and lateral part of the inner dorsolateral protocerebrum (IDLP) of Chiang et al. (2011) (Ito et al., 2014).
