Adult protocerebral bridge 1 glomerulus-fan-shaped body-round body type a neuron (PFR_a) that targets protocerebral bridge glomerulus 2. It targets the same (contralateral) column of the fan-shaped body as PFR_a neurons of the contralateral glomerulus 8, medial to the projection of the glomerulus 1 cell (Lin et al., 2013; Wolff et al., 2015; Hulse et al., 2021). It projects laterally from the fan-shaped body to the contralateral round body (Wolff et al., 2015; Hulse et al., 2021).

PB glomerulus 1 neuron described by Lin et al. (2013) includes both the glomerulus 1 and 2 neurons from Wolff et al. (2015) and later, due to identification of an additional medial PB glomerulus (checked by comparing wiring diagrams). This term refers to the glomerulus 2 neuron of Wolff et al. (2015). This corresponds to the Hanesch et al. (1989) 'horizontal fiber system' neuron of glomerulus 1 (Wolff et al., 2015).
