Abstract
The formation of Metarhodopsin II, measured spectroscopically in the excised bovine retina at 37‡ C, can be described by the sum of two exponentials. The R2 response of a simultaneously recorded early receptor potential can be matched by the difference of two weighted exponentials, whose time constants are identical to those obtained for the spectroscopic signal.
