Comparison of flicker electroretinograms in all mice strains examined under different adaptation and stimulus intensities.

<p>The C57BL/6J mice have normal rod and cone function, the <i>cpfl5</i> mice have pure rod function, and the Rho-^<i>/-</i> mice have pure cone function. Rods respond to low frequency (5 and 15Hz) flicker and cones respond to both low (5 and 15 Hz) and high frequency (25 and 35 Hz) flicker. The <i>rd12</i> mice only responded to low-frequency flicker. + indicates that flicker ERGs existed,—indicates that flicker ERGs did not exist, 5–35 Hz = flicker frequency.
