General Information
Term inferior bridge ID (Ontology) FBbt:00040050 (Fly Anatomy)
Definition Posterior-most synaptic neuropil domain of the midline. It is the only synaptic neuropil domain outside of the central complex that is fused across the midline. It is located behind the fan-shaped body and below the protocerebral bridge.[ FlyBase:FBrf0193607 FlyBase:FBrf0212704 FlyBase:FBrf0224194 ]
Also Known As "IB"
Comment The IB corresponds to part of the superior spsl of Otsuna and Ito (2006). The IB also corresponds to the ventral part of the caudalcentral protocerebrum (CCP) of Chiang et al. (2011) and to part of the posterior inferior protocerebrum (Ito et al., 2014).
