Abstract

The ability of dark-adapted human observers to detect the absorption of a small number of photons challenges our understanding of common neural mechanisms, including G-protein coupled receptor signaling and synaptic transmission. Focused investigation of these neural mechanisms has improved our understanding not only of vision in the dark, but also more generally of how neural circuits can amplify weak inputs and protect them from noise. This chapter summarizes a long history of work on this subject and highlights several issues that have been historically neglected.
