Participants: the control cohort

The control cohort comprised of two samples: first, university students (n = 43) who took part in eyes-closed rest experiments as part of their courses. Second, control participants from the project described in the section above (n = 47). Full informed consent was obtained from all participants. In total, the control sample consisted of 90 participants (65 females), aged between 19 and 55 years (mean: 31.1, SD: 11.8 years). A brief self-report questionnaire was provided to all potential participants, which assessed whether potential participants were suited for inclusion in this study. Exclusion criteria included any history of mental, neuropsychological or neuropathological disorders, as well as the use of recreational drugs in the past 3 months. Demographics of the participants are presented in Supplemental Table S1.
