Linear and superlinear receptive field maps of DNOVS2. a Receptive field of DNOVS2. b Expected receptive field for DNOVS1, calculated by a summation of the receptive fields of VS5 and VS6 (Fig. 2). c DIs between the average receptive field (RF _mean) and each measured receptive field (RF _n) of DNOVS1 (gray dots) and the DI between the average receptive field (RF _mean) and the expected receptive field (RF _exp) marked with a black square. d Contralateral LMS and LPD were recorded while DNOVS2 was depolarized by ipsilateral downward motion. e Receptive field of V2. f “Superlinear receptive field of DNOVS2”, calculated by adding the contralateral local motion sensitivity of DNOVS2 (d) to its receptive field (a). Data represent the mean responses recorded from n flies (DNOVS2 = 3, depolarized DNOVS2 = 3, V2 = 4)
