General Information

Term

superior medial protocerebrum

ID (Ontology)

FBbt:00007055 (Fly Anatomy)

Definition

Medial synaptic neuropil domain of the adult superior neuropils that lies above the area flanked by the mushroom lobes, pedunculus, and calyx. It is separated from the pedunculus by the superior clamp and insulated from the medial lobe by the crepine. The fan-shaped body protrudes deeply into this neuropil, separating it into anterior (ASMP) and posterior (PSMP) regions.[ FlyBase:FBrf0211016 FlyBase:FBrf0212704 FlyBase:FBrf0224194 ]

Also Known As

"SMP"

Comment

Different regions of the SMP correspond to the subdivisions of the smpr and impr (Otsuna and Ito, 2006). The anterior and posterior regions of the superior SMP match part of smpr; the anterior and posterior regions of the inferior SMP match part of impr. The SMP also corresponds to the superior dorsofrontal protocerebrum (SDFP) and to the medial part of the inner dorsolateral protocerebrum (IDLP) of Chiang et al. (2011) (Ito et al., 2014).
