embryonic/larval fan-shaped body - primordial

ID: FBbt_00111207

The primordium of the adult fan-shaped body in the larval posterior inferior protocerebrum (IPp or CPM). It consists of a bilaterally symmetrical slightly curved, horizontal, bar-shaped structure of tufts of filopodia, with undifferentiated synapses, branching off axon bundles stretching from the midline region posterior and adjacent to the mushroom body medial lobe, to a plexus slightly medial to the peduncle. In the late larval brain both halves are interconnected by a plexus of commissural fibers. It is formed by fan-shaped body pioneer neurons in the embryo/early larva and grows during larval development as it is invaded by secondary neurons (Andrade et al., 2019. (Young and Armstrong, 2010, Andrade et al., 2019, Riebli et al., 2013)
