Touchscreen-based training system and learning curves. (a) Touchscreens displayed stimuli and registered responses in the behavior training system. Mice learned to touch the target image and avoid a distractor to get a reward. (b) Mice progressed through a series of pretraining phases (FR, Free Reward; MT, Must Touch; IM, Image) in about two weeks. Pretraining and training on the natural image discrimination (NID) task together took about one month (phases are explained in Methods). (c) Mice learned to perform the NID task to criterion (correct on 85% of trials) in 10 sessions or less, which corresponded to (d) 12 hours or less of training (data in panels c,d are the same, but are plotted against different units on the X-axis).
