Abstract

In a recent paper [ J. Opt. Soc. Am. A 7, 1362 ( 1990)], Stork and Wilson claim that Gaussian derivatives are the real-valued functions that minimize the uncertainty product (Δx)(Δω) and that therefore this series provides a plausible description of single cortical receptive fields. However, there are errors in their analysis, and therefore the claim is wrong.
