  1. The peak velocities of the closing phase of the unconditioned and conditioned responses for the interstimulus intervals (ISIs) of 250 and 500 ms are expressed in mm/s before (PRE) and after (POST) the 5 laser stimulation blocks. Ratios are between the conditioned and unconditioned responses. Results are shown as mean values ± 1 standard deviation (SD).
