adult protocerebral bridge 1 glomerulus-fan-shaped body-lateral accessory lobe neuron [FBbt_00003635]

adult protocerebral bridge 1 glomerulus-fan-shaped body-lateral accessory lobe neuron

ID: FBbt_00003635

Adult central complex neuron that connects a glomerulus of the protocerebral bridge (PB) to a column of the fan-shaped body (FB) and then exits the FB laterally to arborize in the lateral accessory lobe (Hanesch et al., 1989; Lin et al., 2013; Wolff et al., 2015; Hulse et al., 2021). Dendritic arborizations are found throughout the targeted PB glomerulus, but in some cases may extend into neighboring glomeruli (Wolff et al., 2015; Hulse et al., 2021). Arbors in the FB are mainly postsynaptic or mixed and arbors outside of the PB and FB are mainly presynaptic for most of these cell types (Hulse et al., 2021). These neurons follow an approximate nine-column organization in the fan-shaped body (Hulse et al., 2021).

The specific 'horizontal fiber system neurons' described by Hanesch et al. (1989) probably correspond to PFR (protocerebral bridge-fan-shaped body-round body) type a neurons (Wolff et al., 2015). Lin et al. (2013) consider HFS to be equivalent to their PFI neurons - any neuron connecting PB, FB and IDFP (lateral accessory lobe/crepine).
