Effect of green laser light on current-voltage curve of TRPV1-mediated current. (a) Light-activated current in oocytes injected with cRNA for TRPV1; output power 5 mW (circles), 10 mW (triangle up), and 20 mW (triangles down). Data represent averages from 3 oocytes (SEM). (b) Membrane current before (open squares), during (2 min after light was turned on, filled circles), and after irradiation at 40 mW. Data represent averages from 5 oocytes (SEM).
