Single-variable regression and multivariable-regression model coefficients, 95% confidence intervals (CI) for the coefficients, and R 2 values for the model. Areal variable was as follows: MT, 0; LIP, 1. Attentional modulation defined as discussed in Results. Area and attentional modulation variables were each regressed against the single-unit attentional latencies either separately (models 1 and 2) or together (model 3).
