Neurons that target odd or even numbered protocerebral bridge glomeruli target the dorsal or ventral gall, respectively (Lin et al., 2013; Wolff et al., 2015). These neurons receive inhibitory input from delta 7 (PB 18 glomeruli) neurons and they are cholinergic (Turner-Evans et al., 2020). These cells output to P-EN1 neurons and P-EG neurons of the same glomerulus in the protocerebral bridge, and form less specific 'hyper-local' feedback loops with P-EN1 neurons in the EB (Turner-Evans et al., 2020). It also receives input from R4d ring neurons and P-EN2 neurons in the EB (Turner-Evans et al., 2020). adult protocerebral bridge 1 glomerulus-ellipsoid body tile-gall neuron adult protocerebral bridge 1 glomerulus-ellipsoid body tile-nodulus 1 neuron 1 adult protocerebral bridge 1 glomerulus-ellipsoid body tile-nodulus 1 neuron 2 adult intrinsic protocerebral bridge 18 glomeruli-delta7 neuron adult cholinergic neuron
