ML-VPN1 [FBbt_00052138]

Visual projection neuron with its cell body near the anterior proximal medulla and an axonal projection following that of the medulla-lobula neuron 1 (Kind et al., 2021). It has wide-field dendritic arborization in the medulla, spanning tens of columns, ramifying at the border of layers M7/M8, then sending vertical projections to M3 and then to M1, and expanding laterally in each of these layers (Kind et al., 2021). Its main synaptic input from photoreceptors is from R8 cells of pale ommatidia (Kind et al., 2021). It projects to the ipsilateral posterior lateral protocerebrum, innervating a region just behind the optic glomeruli (Kind et al., 2021). There are approximately 65 of these cells per optic lobe (Kind et al., 2021).
