Fig. 2. Preliminary test series. Turning activity of animals in the natural field
(Control) is shown as solid bars and in a field periodically rotated in
periods C and D (Test) as open bars. (A) Unlike the control animals, activity
increases in the test animals after the magnetic treatment is applied and
persists to period E. (B) The contrast in the CDE versus ABF periods
is significant for the Test group (Wilcoxon, N=28, P=0.02)
but not for the Control group (Wilcoxon, N=28, P=0.18). (C)
In the critical CDE period, activity in the Test group is higher then in the
Control group yet not significant (Mann-Whitney, N=28/28,
P=0.08).
