Dynamical adaptation in photoreceptors
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. WebMar 9, 2024 · cAMP is a key regulatory molecule that controls many important processes in the retina, including phototransduction, cell development and death, growth of neural processes, intercellular contacts, retinomotor effects, and so forth. The total content of cAMP changes in the retina in a circadian manner following the natural light cycle, but it also …

WebIt is shown that single cell electrophysiological responses of vertebrate olfactory receptors and of photoreceptors to different input protocols exhibit several common features related to adaptation, and that these features can be used to investigate the dynamical structure of the feedback regulation responsible for the adaptation. Sensory systems adapt, i.e., … WebDec 1, 2000 · Light adaptation occurs at all levels of the visual system, from photoreceptors to central neurons. Yet, the function of the entire visual system depends …
WebThe dynamical adaptation model formulated in recent years is an excellent phenomenological candidate to resume all these phenomena into a single feedforward processing scheme. In this work, we analyze this description in highly nonlinear conditions and find that responses do not match those resulting from a very detailed microscopic … WebNov 1, 2013 · This adaptation is ‘dynamical’ both because it depends upon the temporal structure of the stimulus and because it affects the kinetics of the response. Traditionally, theoretical studies of ...
WebAuthor Summary Photoreceptors constitute the interface between the visual world and the cerebral world, as they convert light inputs into neural signals. This conversion is subject to continuous adaptation: response gain and time scale vary as a function of input history. Webof photoreceptors to different input protocols exhibit several common features related to adaptation, and that these features can be used to investigate the dynamical structure …
WebMar 18, 2013 · The classical rod and cone photoreceptors, on the other hand, mediate image vision by signaling contrast, accomplished by adaptation to light. Experiments by others have indicated that the ipRGCs do, in fact, light-adapt. We found the same but, in addition, have now quantified this light adaptation for the M1 ipRGC subtype.
