Figure 8: Parameter and precision estimates from the analysis of the empirical data presented in the previous figure. Upper left: conditional means (grey bars) and 90% confidence intervals (red bars) of all (eight) free parameters in this nonlinear model. Upper right: the corresponding conditional covariances are shown in image format (with arbitrary scaling). The lower panels show the time-dependent changes in conditional moments as a function of scan number for the parameters (minus their prior expectation; left) and the log-precisions (right). We have focused on the precision of the first (vision) coupling parameter (grey area) in this figure.
