Detection of single photons by toad and mouse rods
Copyright policy )Detection of single photons by toad and mouse rods
SignificanceAmphibian and mammalian rods both detect single photons of light even though mammalian rods are much smaller in diameter. To understand how this is possible, we combined electrical recordings with computations. We show that changes in the rod diameter go hand in hand with changes in the biochemistry to allow for single-photon detection.
