Table 2 Behavioral paradigm: training stages, stimuli, responses, scoring, outcomes and progression criteria
From: A tactile discrimination task to study neuronal dynamics in freely-moving mice
Stage name | Stimulus | Response | Scoring (outcome) | Criterion |
|---|---|---|---|---|
Habituation | 45 mm aperture | Lick | Hit (reward) | ≥ 4 sessions and ≥ 50 successful lick trials |
No lick | Miss (no outcome) | |||
Initial rule | 45 mm aperture | Lick | Hit (reward) | ≥ 4 sessions and ≥ 200 trials above expert-performance threshold (d’ = 1.65) |
No lick | Miss (no outcome) | |||
25 mm aperture | Lick | FA (punishment) | ||
No lick | CR (no outcome) | |||
Neutral aperture stage | 45 mm aperture | Lick | Hit (reward) | 8 sessions in total |
No lick | Miss (no outcome) | |||
35 mm aperture | Lick | No score (no outcome) | ||
No lick | No score (no outcome) | |||
25 mm aperture | Lick | FA (punishment) | ||
No lick | CR (no outcome) | |||
Reversed rule | 45 mm aperture | Lick | FA (punishment) | ≥ 4 sessions and ≥ 200 trials above expert-performance threshold (d’ = 1.65) |
No lick | CR (no outcome) | |||
25 mm aperture | Lick | Hit (reward) | ||
No lick | Miss (no outcome) | |||
Extinction | 45 mm aperture | Lick | No score (random presentation of reward and punishment) | 8 sessions in total |
