t30/30, repeated current applications of 30 s each with a 5 min interval; t60, single current application of 60 s; t60/60, repeated current application of 60 s each with a 5 min interval; t120, single current application of 2 min. Laser Doppler flow (LDF; mean ± s.d.) is expressed in a arbitrary units. Indices for LDF are defined in the text, X, no apparent event.

^*P < 0.05; NS, not significantly different from resting value.
