Experiment 3 results (cross-over study; filtering out light of wavelengths < 380 nm; control group vs. EMF group, n = 8 each): average number of tail lifts, ratio of the number of tail lifts (test-day values divided by baseline values), and increase in the number of tail lifts (test-day values minus baseline values; data shown are mean ± SD per individual per day).

* Two sets of data (that for EMF grouping followed by control grouping and that for control grouping followed by EMF grouping) were merged and underwent analysis. a Ratio = number of tail lifts divided by the baseline number of tail lifts (0.9 ± 0.3 vs. 1.9 ± 0.6 in the control and EMF groups, respectively; n = 8 each, P = 0.02). b Increase in the number of tail lifts = test-day value minus baseline value (−0.5 ± 7.1 vs. 3.7 ± 9.4 in the control and EMF groups, respectively; n = 8 each, p = 0.02).
