Bridging subjective and neural state transitions in the rubber hand illusion: a neurophenomenological study

Neuroscience of Consciousness July 29, 2026 Yukiko Tsuji, Miyuki Azuma, Camille Lépingle et al.

Abstract The rubber hand illusion (RHI) provides a powerful paradigm for probing the malleability of bodily self-consciousness. While conventional studies rely on proprioceptive drift, questionnaires, or averaged neural measures, phenomenological research suggests that the RHI unfolds through multiple subjective state transitions rather than as a simple binary phenomenon. Participants often...

Decrease of Functional Connectivity within the Default Mode Network by a Brief Training of Focused Attention on the Breath in Novices

bioRxiv February 12, 2021 S. Trova, Yukie Tsuji, Haruka Horiuchi et al. preprint

Experienced meditators reduce the activity of the default mode network (DMN), a brain system preferentially active when people are not engaged in specific tasks. However, the neural modulation of the DMN in novices remain largely unexplored. By using electroencephalography, we investigated the DMN functional connectivity in two groups of novices: the meditation group practiced six consecutive...

Brief online mindfulness meditation training modulates heart rate variability during post-stress meditation

Yuki Tsuji, Itsuki Kondo, Sotaro Shimada

Abstract Mindfulness-based interventions are increasingly delivered online, yet evidence for short programs often relies on self-report outcomes. We tested whether a brief online mindfulness meditation training produces detectable changes in autonomic regulation during a standardized stress-to-meditation sequence. Healthy adults with no meditation experience were randomized to a four-week...
