Glutamate and Dysconnection in the Salience Network: Neurochemical, Effective-connectivity, and Computational Evidence in Schizophrenia

The group folder comprises all competing PEBs and a demo script. After saving this folder in the SPM directory in MATLAB, the interested reader can reproduce the Bayesian model comparison procedure by running the relevant script. Furthermore, glutamate data and parameter estimates of sensory PE and prior beliefs can be extracted from any PEB model comprising the relevant regressor. The subjects folder comprises all subjects’ dynamic causal models (including the fMRI timeseries for the relevant regions of interest). The excel file comprises the four conditions of the Stroop task performed by the subjects.
