(2024) identify 'typical' TmY14 that have central brain axon and 'atypical' that do not in FAFB. Unclear if 'atypical' exist in other brains. Transmedullary Y wide-field neuron that terminates in the lobula and lobula plate (Takemura et al., 2013). It displays fine arborizations in medulla layers M3-M5 and M8-M10 (Takemura et al., 2013). Some of these cells have an axon that projects to the central brain, an unusual feature in TmY neurons (Takemura et al., 2013; Shinomiya et al., 2019; Matsliah et al., 2024), but this axon has very few synapses (Matsliah et al., 2024). It is glutamatergic (Konstantinides et al., 2022). TmY14
