A1 Ortiz-García, Andrés A1 Rodríguez-Rodríguez, Ignacio A1 Giménez-de-la-Peña, Almudena K1 Electroencefalografía K1 Dislexia AB Heart Rate Variability (HRV) is a measure of the variationin time between successive heartbeats, reflecting the influence of the au-tonomic nervous system on the heart. It can provide insights into the bal-ance between sympathetic and parasympathetic activity. The relation-ship between autonomic nervous system function, specifically parasym-pathetic activity, and certain learning disorders, including dyslexia, iscurrently under study. In this paper, we propose the use of explain-able techniques to explore the relationships between HRV markers andlocal functional brain activity, estimated by cross-frequency coupling(CFC) from electroencephalography (EEG) signals recorded while audi-tory stimuli were applied to 7-year-old children. We analyze EEG data toexamine the phase-to-phase brainwave coupling and use machine learn-ing tools such as XGBoost and Shapley values to reveal brain regions thatmost contribute to different HRV features, with a focus on parasympa-thetic activity. Our findings suggest that HRV features related to stresscan explain differential activations in the auditory cortex (Brodmannareas 39 and 40) during auditory stimulation in dyslexic children.
