embryonic/larval protocerebral bridge - primordial [FBbt_00111206]

The primordium of the adult protocerebral bridge in the larval brain, formed from the DPMm1 and DPMpm1/2 and CM4 lineages. Unlike in the adult, this exists as a bilateral pair of separate domains that do not join across the midline. These domains are tubular shaped regions containing both differentiated and undifferentiated synapses, in the posterior inferior protocerebrum (IPp or CPM). Each domain curls around the dorsal side from the posterior, growing during the larval period towards the midline. Fusion of the two halves, just posterior to the PLPC (DPLp1) commissure and fan-shaped body, only occurs 48h after pupariation.
