Abstract

Understanding the neural correlates of risk-sensitive skin conductance responses can provide insights into their connection to emotional and cognitive processes. To provide insights into this connection, we studied the cortical correlates of risk-sensitive skin conductance peaks using electroencephalography. Fluctuations in skin conductance responses were elicited while participants played a threat-of-shock card game. Precise temporal information about skin conductance peaks was obtained by applying continuous decomposition analysis on raw electrodermal signals. Shortly preceding skin conductance peaks, we observed a decrease in oscillatory power in the frequency range between 3 and 17 Hz in occipitotemporal cortical areas. Atlas-based analysis indicated the left lingual gyrus as the source of the power decrease. The oscillatory power averaged across 3-17 Hz showed a significant negative relationship with the skin conductance peak amplitude. Our findings indicate a possible interaction between attention and threat perception. NEW & NOTEWORTHY We studied neural oscillations associated with risk-sensitive skin conductance responses. Going beyond previous studies, we applied methods with high-temporal resolution to account for the temporal properties of the sympathetic activity. Preceding skin conductance peaks, we observed decreased occipital cortex oscillatory power and a relationship between the oscillatory power decrease and the skin conductance peak amplitude. Our study suggests an interaction between attention and emotion such as threat perception reflected in skin conductance responses.
