Fig 5. Step down latency (s) for training and test sessions.

Light gray represents the group without returning (first protocol with 3s of stimulus), and dark gray represents the group returning (second protocol with escape latency) in the training session (0.35mA, 62Hz). The latency to escape in the second group is represented in the insert graphic. The data is expressed by median with interquartile range; analyses by Mann-Whitney test; (n = 10 per group) ***p<0.001 comparing to SDT.
