Representative traces of photopic ERG responses, comparing B6 and BTBR mice. (A) Photopic intensity responses. Examples of individual ERG traces recorded at increasing stimulus strengths under 30 cd m⁻² background illumination. Flash onset is at 20 ms. (B) Photopic OFF responses. Examples of individual ERG traces recorded to the offset of an 800 ms square-wave light stimulus, presented at 300 cd∙s m⁻² over a 30 cd m⁻² background illumination. (C) Photopic flicker responses. Representative individual ERG traces recorded at increasing flicker frequencies under 30 cd m⁻² background illumination. Each flash is delivered at 1.37 log cd∙s m⁻². Bandpass is at 0.3–300 Hz for all responses.
