Figure 1.

Families of responses to increasing flash strengths from representative wild-type, knock-out, and hemizygote mice. Responses have been normalized (r/rmax) by the maximal response amplitudes, which were the following (in pA): 16.3 (+/+), 16.1 (-/-), and 17.7 (+/-). Flash strengths (in photons/μm2) ranged from 11 to 4546 (+/+), 11 to 8563 (+/-), and 19 to 8277 (-/-).
