(A) Coherence-response functions for four example cells in two attentional conditions (red curves: attending-out condition; blue curves: attending-in condition). Dashed vertical lines mark the C50 location for each condition. (B) Attentional modulations for the fitting parameters of the coherence-response function (hyperbolic ratio function). Red arrows indicate the mean value of each histogram. Only the Rmax (saturating response) and Rbg (response to 0% coherence) parameters are significantly affected by attention. (C) Correlation between the data and the fit (hyperbolic ratio function) for the attending-outside and attending-inside condition. Dashed lines indicate the median of correlation for each condition.
