Individual cone reflectance changes during light stimulation.

<p>A. AO-SLO image with high magnification (1° * 1°) at 1° temporal from the fovea in Subject 2. White dots represent the 50 cones in which reflectance changes were measured. B. Average of the individual cone reflectance changes during light stimulation. The dark gray lines indicate the raw data. The black line shows the low-pass filtered data at 0.008-Hz. The average cone reflectance changes had two peaks. P1, first positive peak; N1, first negative trough; P2, second positive peak.
