Our findings highlight the role of attention in shaping sensory processing. They expand the use of heart–brain interactions for diagnostics in DoC with an active task that provides multiple layers to explore information processing!

When tested on five brain-injured patients, we found attention-driven changes in cortical responses to heartbeats and brain dynamics in a patient in UWS/VS and in a locked-in syndrome patient, suggesting that patients were engaging with the task! #Consciousness beyond behavior!

We developed subject-specific classifiers using brain dynamical markers (e.g., complexity, mutual information, power). Power features stood out, perfectly classifying attentional focus in all participants.

Heart-focused and sound-focused attention resulted in distinct brain dynamics. We saw differences in PSD slope, complexity, frontal connectivity, and theta oscillations.

Attending to sounds enhanced auditory processing. This was evident not just in responses to target sounds but also to hidden noise repetitions, demonstrating attention's broad impact on sensory encoding.

Focusing on heartbeats modulated heartbeat-evoked potentials (HEPs). These features distinguished between heart-focused and sound-focused attention in 17/20 participants—a robust marker!
