Flowchart of analysis. After segmenting the brain tissues and parcellating the cerebral cortex, BOLD signals were extracted for each tissue type and cortical parcel. The association, β, was computed as the slope relating the time-series of tissue types or parcels with the GS (each dot represents a timepoint). The number of acquired cognitive deficits after surgery (Δ Total cognitive deficits) was correlated with changes in normalised β ($\widehat{\mathsf{\beta }}$) during recovery, Δ$\widehat{\mathsf{\beta }}$.
