The seasonal changes in the size of the receptive field for grooming reflexes induced by 24-h photic and non-photic cycles were determined. Thirteen adult male cats were used in two studies, one study with non-photic factors present in the light phase of 24-h light-dark cycles, and the other study with 24-h non-photic cycles present in constant light. The two studies demonstrated that non-photic cycles are essential and sufficient in controlling the size of the receptive field for grooming reflexes. Analysis of variance of the daily patterns of activity indicated that significant differences were present whenever the cycles were effective in changing the size of the receptive field. The main difference in the daily activity patterns was the temporal relationship between “morning”; and “evening”; peaks, and this relationship was discussed in terms of the internal coincidence model for photoperiodic induction. |
