The above attention shows that at this time a few of the experi­ psychological evidence on playstation in animals may be quantitatively defined in the limits of the "universal" photoreceptor membrane notion. in fact, life of preferential orientation of the soaking up dipoles within the tubuli of the rhabdomeres can't be completely rejected. we are hoping that the concept that of the "universal" photoreceptor membrane could function the valuable device whilst facing newly chanced on houses of visible cells in order that real mechanisms of electric and optical coupling may be sought for rather than assumptions being made on extra homes of the photoreceptor membrane in each new animal less than examine. five. Absorption Spectrum of the common Photoreceptor Membrane and Spectral Sensitivity of the Photoreceptor five. 1 initial Notes it sort of feels approximately self-evident that the absorption spectrum of the pho­ toreceptor membrane coincides precisely with that of the visible pigment it comprises. for that reason, the membrane needs to show 3 bands of absorp­ tion - the crucial band with its top in the limits of seen spectrum (or a-peak); the secondary band among 340 and 380 nm (S­ peak); and the 3rd, protein band, within the ultraviolet (UV) at 280 nm (COLLINS et al. , 1952). the most top of absorption is found in the variety 433-575 nm for retinol-based pigments and among 438 and 620 nm for 3-dehydroretinol-based pigments, the placement of Amax de­ pending on many ecological factors.
