FIG. 3. The time course of stimulation-produced bite-and-kick attack, mounting, mounting by the opponent, and locomotion. The figure includes data from the 8 sites with attack, the 12 sites with mounting, the 10 sites with mounting by the opponent, and 26 of the 35 sites with persistent locomotion. Systematic, minute-by-minute data were not recorded for nine other sites with persistent locomotion.
