Adult medulla-tubercle (MeTu) neuron that receives input from R7 (and not R8) photoreceptors of the dorsal rim area (DRA) in the proximal part of medulla layer M6 (Kind et al, 2021). Its arbors span several columns, and may include columns outside of the DRA, though its non-DRA arbors are just proximal to M6, avoiding photoreceptor terminals (Kind et al., 2021). It has presynaptic sites in the small unit of the anterior optic tubercle, in a region distinct from the terminals of non-DRA MeTu neurons (Kind et al, 2021).
Visual projection neuron that receives input in the medulla dorsal rim area and sends output to the posterior lateral protocerebrum (Kind et al., 2021).
Visual projection neuron that has tangential arborization in the medulla (Kind et al., 2021).
Medulla tangential projection neuron that has processes in medulla layer M7 and branches reaching up to M5-M6 (Kind et al., 2021). It receives input from several R7 photoreceptor cells (Kind et al., 2021). It projects an axon to the posterior lateral protocerebrum (Kind et al., 2021).
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).
Visual projection neuron with its soma in the cell body rind of the medulla and dendritic innervation of medulla layers M7/M8 (Kind et al., 2021).
