sequence detection task mouse: basic stimuli presentation Phase 1: need to have a sequence of visual stimuli (gratings) drawn (time fixed, with only background in between) based on a 4-element unidirectional loop the first stimuli should be randomized. The following stimuli should follow in sequential order (ie a-b-c, b-c-d, c-d-a, d-a-b). Randomize a sequence, with each number identifying a specific angle for the grate. (once it works, also have link the identifier to the temporal frequency (1-4)
Phase 2: integrate incorrect trials option to randomize (at a specified probability) the 1st, 2nd and/or 3rd stimuli with an unfamiliar/very different stimuli (blue square or whatever) start with all stimuli wrong, then 2, then 1
Phase 3: integrate incorrect trials with familiar stimuli option to randomize (at a specified probability) the 1st, 2nd, or 3rd stimuli with the last unused stimuli in the loop (ie if correct is b-c-d, swap one of them for a)
Phase 4: integrate incorrect trials with only one characteristic (grate or temporal frequency) incorrect option (on 10-30% of trials) to swap the wrong direction or temporal frequency only of the 1st, 2nd, or 3rd stimuli first with unfamiliar stimuli characteristic, ie b-c-d turns into b-c-d(random angle OR speed) next, within the familiar stimuli ie b-c-d turns into b-c-d (with angle or speed from stimuli a)
Need to integrate lick input after last stimuli in each trial is presented if mouse licks on correct, then reward, and reward tone->next trial start if mouse licks on incorrect, no reward, time out (different background color, black?), white noise->next trial start
speed detection, lick rate detection
