Sigmoidal and Gaussian curves were fit to the responses as a function of sound location using a nonlinear least-squares regression method. The column labeled ″% of fits″ gives the fraction of the total population of cells fit by at least one function (p < 0.05) (i.e., line A, B, or C divided by line D). The results of the ANOVA for the full time period are provided for comparison.
