Hr. Matthews et Gl. Fain, REDUCED CYTOPLASMIC CALCIUM-CONCENTRATION MAY BE BOTH NECESSARY AND SUFFICIENT FOR PHOTORECEPTOR LIGHT ADAPTATION, Behavioral and brain sciences, 18(3), 1995, pp. 481-481
Light adaptation is modulated almost exclusively by changes in intrace
llular Ca2+ concentration, and other Ca2+-independent mechanisms are l
ikely to play only a minor role. Changes in Ca2+i may be not only nece
ssary for light adaptation to take place but sufficient to cause it.
