Results of PPI analysis. (A) Exemplary data from an individual participant who had a decrease in left primary motor (M1) ‐ left dorsal premotor cortex (PMd) connectivity during the action selection (AS) condition compared to the execution only (EO) condition (each data point represents activity for a single brain volume). Slope and correlation coefficient (r) were extracted for each participant and condition. (B) The same participant showed an increase in PMd – left dorsolateral prefrontal (DLPFC) connectivity during AS compared to EO. (C) Change in M1‐PMd connectivity (AS slope – EO slope) plotted against RT cost separately for each group. A positive change equates to an increase in connectivity while a negative change equates to a decrease in connectivity from the EO to the AS conditions. (D) Change in PMd‐DLPFC connectivity (AS slope – EO slope) plotted against RT cost separately for each group. *significant correlation at P < 0.05.
