Temporal Scaling of Human Scalp-Recorded Potentials During Interval Estimation

<jats:title>Abstract</jats:title><jats:p>Standard event-related potential analysis assumes fixed-latency responses relative to experimental events – yet recent single unit recordings have revealed neural activity <jats:italic>scales</jats:italic> to span different durations during behaviours demanding flexible timing. We use a novel approach to unmix fixed-time and scaled-time components in human electroencephalography, recorded across three tasks. A consistent and distinct scaled-time component is revealed, demonstrating temporal scaling can reliably be measured at the scalp.</jats:p>
