part of synaptic neuropil domain inferior neuropils antler posterior inferior protocerebrum pimpr CCP fly_anatomy.ontology FBbt:00045039 VFB:FBbt_00045039 Thin, elongated, antler-shaped, bilaterally paired synaptic neuropil domain spanning from the inferior bridge to the inferior edge of the superior lateral protocerebrum. It runs through the space between the protocerebral bridge and the fan-shaped body, along the medial surface of the medial antennal lobe tract. ATL IPp The antler corresponds to part of the medial part of the pimpr of Otsuna and Ito (2006) and to the dorsal part of the caudalcentral protocerebrum (CCP) of Chiang et al. (2011) and to part of the posterior inferior protocerebrum (Ito et al., 2014).
