Interval between bursts, 27 seconds. Fre- quency, 40 shocks per second. Drum stationary. A, physostigmine applied by drip method during experiment. B, muscle strip immersed in physostigmine for 15 min- utes previous to stimulation. The effect of physostigmine on the responses to a series of single shocks was to produce a striking augmentation.

. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. FIG. 7. Effect of physostigmine, 1 ,000 cc., on the responses of muscle strip to a series of bursts of stimuli. Interval between bursts, 27 seconds. Fre- quency, 40 shocks per second. Drum stationary. A, physostigmine applied by drip method during experiment. B, muscle strip immersed in physostigmine for 15 min- utes previous to stimulation. The effect of physostigmine on the responses to a series of single shocks was to produce a striking augmentation. The whole worm preparation was stimulated for 5 seconds at a low frequency of 7 shocks in 5 seconds. This was followed by a 3-minute period of rest during which the preparation was given Ringer's solution by drip method. Figure 6, A shows a series of five of these 5-second stimulations. Within each of the five groups there is an increase in the successive responses, but the facilitation decays during the 3-minute rest period, so that the first response in each of the five groups is of the same magnitude. Figure 6, B shows the result of repeating this procedure except that physostigmine drip 1 ,000 cc. was substituted for the Ringer's. ARY :.
