Extended Data Fig. 7: Supporting circadian and electrophysiology data for main text Figs. 3 and 4.

(a). Raw AP counts for each aCC neuron recorded expressing Dmcry^V531K in the 15 s before vs. the following 15 s during BL±MF, from which the average firing-fold change was derived for data reported in main text Fig. 3c. BL: n = 10, BL+MF: n = 10. Paired t-tests – two tailed, were used to compare before vs. during for cells exposed to BL (left hand graph) or to BL±MF exposure (right hand graph). MF-potentiation between the two groups was tested by unpaired t-tests – two tailed (different cells). (b). Dmcry^M flies do not undergo period shortening following exposure to a 50 µT MF (DD n = 26, BL Pre-Sham n = 51, BL+Sham n = 42, BL Pre-MF n = 53, BL+MF n = 38). (c). Raw AP counts for BL and BL+MF exposure for ErCRY4, showing an increase in neuronal excitability to both stimuli (BL: n = 8, BL+MF: n = 9). Paired t-tests – two tailed were used to compare before vs. during for cells exposed to BL (left hand graph) or to BL±MF exposure (right hand graph). MF-potentiation between the two groups was tested by unpaired t-tests – two tailed (different cells). The reported n for each electrophysiological recording is derived from independent cells from biologically independent animals. The reported n for each circadian period derives from biologically independent animals. Error bars denote ±SEM, ns p ≥ 0.06, *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001.
