Most of its fan-shaped body synapses are found in layers 4 and 5 (Hulse et al., 2021). There is a two-column ipsilateral phase shift between the PB and FB, such that the medial (glomerulus 5) cell in each hemisphere of the PB targets a column of the FB two columns from the central column in the same hemisphere (Hulse et al., 2021). These cells collectively target PB glomeruli 1-7 with around 1-3 cells per glomerulus (Hulse et al., 2021).
