Abstract
We analyzed multimodal electrophysiological signals from 144 adults (63 Males; Mage=24.3) to develop interpretable predictive and causal models of acute stress. The predictive model achieved excellent test accuracy (85.37%) and identified key neural and cardiorespiratory features. Causal discovery analyses revealed stress-induced disruption of bottom-up inspiratory influences on frontal neural activity.
