WebDec 22, 2005 · A standard feature of photoreceptor adaptation to background illumination is “desensitization,” a reduction in sensitivity relative to that observable in the dark-adapted state ( Perlman and Normann, 1998 ). Light exposure clearly desensitizes ipRGCs. WebKrizaj's lab demonstrated for the first time that dynamic regulation of SERCA transporters and ryanodine receptors that release calcium from internal stores is essential for transmission of the visual signal from photoreceptors.
