Essential medications in palliative care: an updated survey of Australian and New Zealand medical practitioners practising palliative care.

A growing body of (see ) research links key features of social communication to the extent to which neurophysiological activity becomes coupled across individuals: fluctuations in are impacted by shared engagement and social behaviors and, critically, contribute to social learning and bonding , , , . Recent findings from our group and others suggest that providing through visual, auditory, or haptic information about ongoing synchrony fluctuations may boost social outcomes (A,B , , , ). Multi-brain neurofeedback: implementation and hierarchical theoretical framework. (A) Representative multi-brain/body feedback interfaces developed by our team over the past decade, engaging thousands of dyads and groups. Examples include: (i) Mutual Wave Machine , (ii) Mutual Brainwaves Lab (incl. collaboration with Bad Bunny and Residente, not pictured) , , (iii) Compatibility Racer, (iv) Harmonic Dissonance, (v) Measuring the Magic of Mutual Gaze (ft. Marina Abramović), (vi) XenBox (ft. Mike Gordon and Bob Weir, Grateful Dead). (B) A typical multi-brain neurofeedback implementation. During naturalistic social interaction, neural signals are simultaneously acquired from multiple individuals and transformed into indices of interbrain synchrony, which are fed back in real time to support regulation of coupled neural activity. For illustrative purposes, the figure depicts a visual interface; however, feedback interfaces can be auditory, tactile, robotic, etc. (A). (C) Hierarchical levels of multi-brain neurofeedback training. Training targets can be defined at multiple levels of organization.
