part of synaptic neuropil subdomain lateral zone of anterior optic tubercle 2020-02-17T15:39:07Z lateral anterior optic tubercle L-AOTU The region of the anterior optic tubercle with the most dense labelling of fibers and synapses (Ito et al., 2014). It contains the terminals of MC61 neurons (Otsuna and Ito, 2006; Hulse et al., 2021; Timaeus et al., 2020). AOTUl fly_anatomy.ontology VFB:FBbt_00047046 FBbt:00047046 optu3 AOTU lateral compartment Timaeus et al. (2020) divide this into 4 (central and lateral x anterior and posterior), whereas Tai et al. (2020) divide this into 3 (along medial-lateral axis with no description of anterior-posterior axis). Hemibrain types (TuBu06-10) seem to correspond better to 2x2 than 3x1. Based on innervating TuBu types, this contains AOTUlp, AOTUlc, AOTUla and AOTUil of Omoto et al. (2017) and Kandimalla et al. (2023). small unit of anterior optic tubercle
