Photosensitivity of Chromatophores

Acetyl Choline and Chromatophores.

Cytomatrix in chromatophores

Although intracellular transport is a fascinating and vital function shared by diverse cell systems, our understanding of the processes involved remains incomplete, despite the enormous amount of attention it has received over the past 40 years (46). Recent work on pigment granule transport in chromatophores (e .g ., erythrophores, melanophores, and xanthophores), however, has begun to yield ne...

Physiology of human photosensitivity.

Human epileptic photosensitivity has been studied in several ways. (a) Visual stimulation that resembles the stimulation normally responsible for seizures, such as that from televisions or videogames, both of which typically use cathode ray tubes in which the display is created in a flickering pattern. Such stimulation is often rendered yet more epileptogenic by programmes with content that als...

Photosensitivity Spectrum of Crayfish

Discrepancies exist among spectral measurements of sensitivity of crayfish photoreceptors, their absorption in situ, and the number and absorption spectra of crayfish photopigments that are extracted by digitonin solutions. We have determined the photosensitivity spectrum ofcrayfish rhodopsin in isolated rhabdoms using long wavelength fluorescence emission from crayfish metarhodopsin as an intr...

Electron microscopy of chromatophores of Rhodopseudomonas spheroides.

Gibson, K. D. (St. Mary's Hospital Medical School, London, England). Electron microscopy of Rhodopseudomonas spheroides. J. Bacteriol. 90:1059-1072. 1965.-Fixed and stained chromatophores and whole cells of anaerobically grown Rhodopseudomonas spheroides were examined in thin sections in the electron microscope. Both purified chromatophores and intracellular membrane-bound vesicles had exactly ...
