Table 1. Drivers and neuron types used.

When the ‘Driver’ name is followed by an insertion site, it is a LexA line (see Materials and methods). Names starting by SS are stable splits. All other driver names correspond to both Gal4 (in attP2) and LexA (in attP40) drivers. ‘New Type Name’ refers to the nomenclature for short names adopted in this paper (following [Kakaria and de Bivort, 2017; Turner-Evans et al., 2017; Green et al., 2017]). Type description is the long name, following the guidelines of Wolff et al. (2015). Pre and post regions are labeled based on anatomical characteristics. The finer subdivisions were used to establish if two neurons were anatomically overlapping. The corresponding name in other insect species were determined using the insect brain database (https://insectbraindb.org/) and related papers (Heinze and Homberg, 2008; Heinze and Reppert, 2011b; Stone et al., 2017)
