My early career research was associated with bioelectrical brain index of automatic change-detection which is elicited following any change to an established regularity in auditory stimuli. My studies demonstrated brain localization of “prediction error” responses to simple and abstract features of auditory environment (Korzyukov et al., 1999, 2003).

 

My research in auditory gating, first time demonstrated presence of frontal lobe contribution to brain mechanisms of auditory sensory gating in human (Korzyukov et al., 2007, 2009). These results advanced our understanding of brain mechanisms underlying normal development of children and pathological brain changes resulting in schizophrenia.

 

My research of voice auditory feedback during vocalizations resulted in demonstration of clinical (Amusia, Korzyukov et al., 2012; ADHD, Korzyukov et al., 2015) applicability of techniques for measuring bioelectrical brain responses to changes in voice pitch auditory feedback. My study of Sense of Agency first time demonstrated brain indexes of self-agency associated with brain control of vocalizations (Korzyukov et al., 2017).

 

My studies of predictive processing for aggregation of auditory and vocal brain systems across hierarchically organized time scales first time demonstrated that formation of expectancy for auditory-controlled vocal brain system, within the time range of seconds, resulted in two sequential neuronal processes. (Korzyukov et al., 2012, 2020). Finding from these experiments is opening avenue for validation of the predictive processing theory at more macroscopic level of brain organization.
