Visual pigment has been regenerated in normal human retinas, 5 to 58 hours postmorten, by exposure to retinal isomers in the dark. Levels from 0.1 to 0.41 nmol/ mg protein were reached. Photoresponses were obtained in 9 of 13 retinas: P III maximum amplitudes ranged from 20-398 μV and thresholds, taking the criterion amplitude as 3 μV, ranged from 8.8-1340 quanta/μm 2. In three cases, the b-wave was also seen. The P III amplitude vs. log intensity curves gave values of n between 0.6 and 1.0, and σ (the stimulus intensity for a half maximal response) between 132-3700 quanta/μm2. Recovery of sensitivity did not always correspond to that of maximum response.
