This experiment determined the threshold stimulation intensity needed for production of retrograde amnesia with 60 Hz caudate stimulation. With the stimulation parameters used, the necessary intensity is between 1 and 1.5 mA. This stimulation is an effective amnesic agent when administered 15 min, but not 60 min, after training. The possibility that these results relate to brain seizure thresholds, and only secondarily to retrograde amnesia thresholds, is considered.
