“…Higher event-related alpha band desynchronization in anxious individuals has been already reported previously (Aftanas et al, 1996;Knyazev et al, 2006Knyazev et al, , 2008a. The between-group differences in reactivity of high and low antero-posterior gradient participants essentially replicate findings previously reported for comparison of high and low anxiety subjects.…”

“…Therefore, we used data from two different studies with very different experimental tasks. In the first study, participants were presented with emotionally loaded visual stimuli (emotional facial expressions) and asked to evaluate the presented stimuli in terms of their emotional content (for a detailed description of this study see Knyazev et al, 2008a). In the second study, a stopsignal experimental paradigm was used.…”

“…This evidence appears to suggest that event-related theta band synchronization could with a reasonable confidence be treated as an electrophysiological manifestation of emotional information processing. Theta synchronization upon presentation of emotional facial expressions has been also noted in several studies [Basar et al, 2006;Gu¨ntekin and Basar, 2007;Knyazev et al, 2008a]. Thus, it could be suggested that predominantly cognitive processing of sensory stimuli should be manifested by a higher eventrelated alpha band desynchronization, whereas predominantly emotional responding should be associated with higher event-related theta band synchronization.…”

Hostility is associated with biases in the perception of emotional facial expressions, such that ambiguous or neutral expressions tend to be perceived as threatening or angry. In this study, the effects of hostility and gender on the perception of angry, neutral, and happy faces and on the oscillatory dynamics of cortical responses elicited by these presentations were investigated using time-frequency decomposition by means of wavelet transforms. Feelings of hostility predisposed subjects to perceive happy and neutral faces as less friendly. This effect was more pronounced in women. In hostile subjects, presentation of emotional facial expressions also evoked stronger posterior synchronization in the theta and diminished desynchronization in the alpha band. This may signify a prevalence of emotional responding over cognitive processing. These effects were also more pronounced in females. Hostile females, but not hostile males, additionally showed a widespread synchronization in the alpha band. This synchronization is tentatively explained as a manifestation of inhibitory control which is present in aggressive females, but not in aggressive males.

“…1). The activity of the theta band has been linked with emotional influences on perception in anxious people [26,27]. Neurobiology studies have suggested that the premotor cortex incorporates both a representation of peripersonal space and defensive-like motor repertories [28].…”
