Abstract
This paper presents a new analysis of the contrast flash data of Alpern et al. (1970a-d). It was prompted by the criticism of Wandell (1976) who pointed out that Alpern et al., main conclusion, i.e. that the inhibitory signal N *(ϕ) elicited by the contrast flash (ϕ) takes the form \(N^ * (\phi ) = \frac{\phi }{{\phi + \sigma }}\), would imply an unrealistic excitatory photo response. The present analysis shows the data to be consistent with an inhibitory signal of the form \(N^ * (\phi ) = \left( {\frac{\phi }{{\phi + \sigma }}} \right)^n \).
