Fig. 4.
Graphical representation of the noncoupled ON cone bipolar (ONCB) percentages of all tissues analyzed for glycine coupling. Each symbol in the key represents retina sections from a single rabbit. They are all divided into four categories of tissue state and are represented as follows: SL, light-adapted superior tissue; IL, light-adapted inferior tissue; SD, dark-adapted superior tissue; and ID, dark-adapted inferior tissue. Rabbits 1 and 2 were sacrificed on the same day. Rabbit 1 was dark adapted for 12 hours and then light adapted for 3 hours. Rabbit 2 was dark adapted for 15 hours. Rabbits 3 and 4 were sacrificed on the same day and were light or dark adapted for 3 hours prior to surgery. The remaining rabbits were adapted for 2 or 3 hours each.
