Figure 1. Effect of repeated aversive stimulation on the heart rate increase (HR, closed circles) and time until basal heart rate recovery (RT, open circles) in intact specimens of Megalobulimus mogianensis. A group of 10 snails was tested. Data are reported as means ± SEM for 6 to 9 legible recordings as indicated to the right of each point in the figure. Heart rate data are reported as beats per minute (bpm), and recovery time is reported as min at 25ºC.
