MeTu [FBbt_00051228]

Neuron that connects the medulla to the anterior optic tubercle (AOTU), via the anterior optic tract, innervating the small unit of the AOTU (Timaeus et al., 2020; Hulse et al., 2021; Kandimalla et al., 2023). It is derived from an optic neuroblast (Kandimalla et al., 2023). There are around 500 of these cells per hemisphere (Nern et al., 2025).
