Additional Information
Statement
Reference

This GAL4 line drives expression in hygrosensitive neurons in the second chamber of the sacculus.

(Sun et al., 2018)

ScerGAL4Ir68a.PK drives expression in approximately 10 neurons that make up antennal lobe glomerrulus VP5, these project to chamber II of sacculus, these neurons also overlap with expression of Ir25a and Ir93a.
