Spontaneous pupil fluctuations (SPFs) during rest provide a non-invasive, low-cost index of central arousal dynamics, independent of cognitive task demands. These features position SPFs as promising markers for baseline neurophysiological activity in both basic and translational research. This review synthesizes current evidence on the resting-state pupil-brain system, focusing on its core...
Mindfulness-based interventions improve psychological well-being but their effects on neurophysiological measures remain inconsistent. Traditional group-averaging approaches may overlook inter-individual variability, leaving doubts about if and how MBIs can influence one’s well-being. This study investigates the effect of Integral Meditation (IM) on behavioural and neurophysiological outcomes...
