Breathing, beyond its metabolic role, has been increasingly implicated in shaping perception, attention, and aspects of cognitive processing. Here, we propose the Rhythmic Embodied Perception (REP) Framework, a multi-level framework linking body and brain to explain how respiration structures conscious experience. At the neurophysiological level, slow respiratory cycles modulate cortical...
Growing evidence demonstrates that meditation practice supports cognitive functions, including attention and interoceptive processing, and is associated with structural changes across cortical networks, including prefrontal regions and the insula. However, the extent of subcortical morphometric changes linked to meditation practice is less appreciated. A noteworthy candidate is the pineal...

Abstract Mind-wandering is typically characterized by the common experience wherein attention veers off into thoughts unrelated to the task at hand. Recent research highlights the intentionality dimension of mind-wandering as a key predictor of adverse functional outcomes with intentional and unintentional task-unrelated thought (TUT) differentially linked to neural, behavioral, clinical, and...
Abstract The locus coeruleus (LC) has established functions in both attention and respiration. Good attentional performance requires optimal levels of tonic LC activity, and must be matched to task consistently. LC neurons are chemosensitive, causing respiratory phrenic nerve firing to increase frequency with higher CO 2 levels, and as CO 2 level varies with the phase of respiration, tonic LC...
