“…These magnitudes are well beyond what one might expect as day-by-day fluctuations, especially for rats that had achieved 48 or more trials of convulsions. Presumably, 3·Hz stimulation increases the ETL Thus, the intensity has to be increased to elicit a convulsion, or else the ETI decreases over the early test trials with 600Hz stimulation, as in the beginning trials (Tress & Herberg, 1972).…”

These exploratory experiments investigated the effect of 3·Hz brain stimulation on behavior induced by 60·Hz brain stimulation when the former was presented simultaneously with, or following, the latter. In the simultaneous case, 3-Hz stimulation to one amygdala and 60 Hz to the other produced a slower kindling rate than did bilateral stimulation with 60 Hz. When 3-Hz stimulation followed six convulsion trials of 60-Hz stimulation, there was no effect on the convulsive tendency; however, with rats in which the convulsive pattern was relatively stable and 48 or more convulsive trials were followed by 24 trials of 3·Hz stimulation at double intensity or 36 trials at the same intensity as previous 60-Hz stimulation, a reversal effect was observed, that is, a return to nonconvulsive behavior.

“…In the preliminary experiment and another Six trials of convulsions as used in Experiment 3 do not produce stable behavior on the part of rats. The intensity of stimulation required to produce a convulsion decreases over trials quite drastically in early trials (Tress & Herberg, 1972) .…”

“…Furthermore, oscillation should occur over only a few phases and then disappear, because periodic stimulation lowers the threshold for seizure and both sides should become equally efficient (Tress & Herberg, 1972). However, although there are a few rats which terminate oscillation after a few phases, most continue to oscillate throughout the entire series of phases, especially in the latency measure.…”

“…This suggests that 5V is better than 1V and as effective as 20V. Determining the least amount of electricity needed to get the best effect is important in the septum, since this nucleus is prone to inducing seizure with overstimulation (Tress & Herberg, 1972;Duchowny & Burchfiel, 1981). There were no differences in the amount of inhibition any one parameter of electrical stimulation caused for pressure and pinch.…”
