The Neural Basis of Consciousness During Evening Naps Measured by MEG: A Registered Report
Chikayo Hemmi, Angus Leung, Jennifer Windt et al. preprint
The neural correlates of dreaming remain uncertain, especially regarding which brain regions and frequency bands reliably reflect conscious experience during sleep. This registered report describes a study that will use magnetoencephalography (MEG) during evening naps with a targeted serial-awakening paradigm to test whether previously reported EEG-based correlates of dreaming generalize to MEG. Pilot data from one participant supported hypotheses about low-frequency power across frontal and posterior regions but not high-frequency power; another participant provided insufficient evidence. An independent analysis team will test the pre-specified hypotheses on the remaining 10 participants who meet inclusion criteria.
