ScerGAL4ple.TH-F-1 drives expression in a subset of the dopaminergic neurons in the adult brain labelled by ScerGAL4ple.PF : around 4 PPM2 neurons, 5 PPM3 neurons (of the mFB and vFB types), 4 PPL1 neurons (of the DP, MB-V1, MB-MV1, MP-MP1 and MB-alpha types) and 1 PPL2 neuron. There was also some non-systematic expression in less than 1 neuron in the PAM cluster.
