Figure A.1.

Single instance cone mosaic responses to the null and a test stimulus depicted at the time of peak response. (A) Cone mosaic photopigment excitation response instance to the null stimulus (uniform field with a background of 34 cd/m²). (B) Cone mosaic photopigment response instance to a test stimulus, here a 16 c/deg, 100% contrast, 34 cd/m² mean luminance grating stimulus. (C) Cone mosaic photocurrent mosaic response instance to the null stimulus. (D) Cone mosaic photocurrent mosaic response instance to the same test stimulus as in (B).
