| Monkey B | ||||
| 1 | Area (MT/LIP) | −54 | −85 to −22 | 0.19 |
| 2 | Attentional modulation (spikes/s) | −1.2 | −2.5 to 0.04 | 0.07 |

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).
