Figure 4. Comparison of ERGs obtained to 7 min stimuli from control and Kir4.1 mutant mice
ERGs recorded to 7 min duration stimulus flashes from Kir4.1+/+/nob (thin blue tracing) or Kir4.1+/-/nob (thick red tracing) mice. Each record indicates the grand average of 3 Kir4.1+/+/nob or 7 Kir4.1+/-/nob mice. Stimulus intensity was 2.2 cd/m2. Stimulus presentation is represented by the lower trace. Amplitude calibration indicates 1 mV.
