Empirical data: This figure illustrates the data used for the empirical illustration of model selection. Regional summaries were harvested from six regions of interest using the attention to motion paradigm described in the main text. The central location of each region is shown on the left, superimposed on a translucent (canonical) cortical surface in MNI space. The resulting principle eigenvariate (summarising observed responses) are shown in the right panels. In this example, we can see evoked responses in visual areas (every 60 s) with a progressive loss of stimulus-bound activity and a hint of attentional modulation and other fluctuations in higher regions. The predictions of these dynamics, based on inferred hidden states are shown in the next figure.
