Delta-Alpha EEG pattern reflects the interoceptive focus effect on interpersonal motor synchronization

Little is known about how the modulation of interoceptive focus impacts neural correlates high-level social processes, such as synchronization mechanisms. Therefore, current study aims to explore intraindividual electrophysiological (EEG) patterns induced by on breath when performing cognitive and motor tasks requiring interpersonal synchronization. A sample 28 healthy caucasian adults was recruited asked perform two during distinct conditions: while focusing or without breath. EEG frequency bands (delta, theta, alpha, beta band) were recorded from frontal, temporo-central, parieto-occipital regions interest. Significant results observed for delta alpha bands. Notably, higher mean values desynchronization in temporo-central area condition compared task. Taken together these could be interpreted considering functional meaning band relation Indeed, oscillations shape dynamics behaviors attenuation previously generation, observation, imagery movement considered reflect cortical activity action-perception coupling. Overall, research shows that an delta-alpha pattern emerges areas at intra-individual level, indicating attention visceral signals, particularly synchrony.
