Abstract

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.
