Principles of oscillatory brain dynamics and a treatise of recognition of faces and facial expressions

Facial affect manifested by multiple oscillations

“…Başar et al (2006Başar et al ( , 2007 also found higher occipital delta responses both upon known and unknown faces. Balconi and Lucchiari (2006) observed maximal delta synchronization in the posterior regions for all types of facial expression stimuli.…”

“…In a series of publications on "face recognition" we have reported differentiations of "known" and "unknown" faces by using several oscillatory components (Başar et al, 2006. Furthermore, EROs of facial expressions yielded relevant differentiation between responses to angry and happy face expressions in the alpha and beta frequency ranges (Güntekin and Başar, 2007).…”

Hostility‐ and gender‐related differences in oscillatory responses to emotional facial expressions

“…Considerable evidence confirms a link between emotional responding and an increase in theta power both in animals [Mitchell et al, 2008;Moita et al, 2003;Pare, 2003;Pare and Collins, 2000;Sainsbury and Montoya, 1984;Seidenbecher et al, 2003] and in human beings [Aftanas et al, 2001[Aftanas et al, , 2004Basar et al, 2006;Doppelmayr et al, 2002;Krause et al, 2000;Nishitani, 2003]. 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.…”

“…Balconi and Lucchiari [2006] reported desynchronization of alpha and beta oscillations on presentation of all types of facial stimuli. Basar et al [2006] demonstrated highly increased occipital theta responses on stimulation with angry faces. In a recent study, Gu¨ntekin and Basar [2007] showed that differentiation between angry and happy facial expressions was observed especially in the alpha and beta frequencies.…”

Event-related potentials and event-related oscillations during identity and facial emotional processing in schizophrenia

“…Basar and colleagues have used oscillatory activities to assess face recognition (Özgören et al, 2005;Basar et al, 2006). They showed differences during recognition of the own grandmother's face and an older woman (unknown face) in different frequency bands, especially in beta and theta oscillations.…”
