  3. Notable Paper: The Molecular Mechanism of Thermal Noise in Rod Photoreceptors

      Phototransduction is the process by which photon capture by opsins in photoreceptors is transduced into a neural signal.    However, there are limits on visual sensitivity that are imposed by thermal means as opposed to the photochemical mechanisms resulting in activation of the phototransduction cascade. The mechanism of this limit has long been a […]
