Toad and frog rod photocurrents

The size of Bufo marinus and Rana pipiens rod photocurrents is similar affected by changes in flash intensity. These species rods produce similar photocurrents during steady illumination, to which they both adapt. Thus, their transduction mechanisms are probably alike. Previous reports that frog and toad rod responses are different may have resulted from the use of an unusual procedure in which the rod outer segment was isolated from its inner segment.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/23978/1/0000227.pd
