Symposium: Oscillatory systems of the brain, their role in the management of mental processes, behavior, and individual differences Symposium Chair: Vilfredo De Pascalis (Italy) and Nina Danilova (Russia) During the past twenty years, experimental research on EEC oscillations has evidenced significant associations of oscillatory brain activity with cognitive and memory performance. A main goal of the current research was to determine how brain structures jointly engaged by a task interact with each other. Such interactions may provide crucial insights into the ways in which oscillatory processes are generated within the human brain and how such oscillations serve to organize cognitive processes. Parallel approaches, linking individual differences in sensory and cognitive information processing to learning ability and personality, yielded robust effects in several paradigms. In this symposium, the progress in experimental research in memory, learning and individual differences in personality traits is exploited using resting and event-related EEC recording methods. The symposium begins with an innovative study on working memory demonstrating the role of frequency-selective generators and evidencing the brain structure and oscillatory dynamics of mental processes connected with the identifica¬tion of target and non-target stimuli. This is followed by a recent work showing how training can influence behavioral abilities and the associated neuroelectrical (ERD/ERS) and hemodynamic (N1RS) pat¬terns of brain activity. A third study, using independent component analysis (ICA) and source localization techniques of EEC data, has evidenced theta activity as a main predictor of agentic extraversion. Agentic extraversion, as compared with other personality dimensions, is also suggested as a better predictor of posterior versus frontal activity. Finally, recent findings are presented showing that greater relative left-sided asymmetry in the middle and inferior frontal gyri is associated with facets of Behavioral Approach System (BAS), while Positive Orientation (a measure of psychological functioning and well-being including Self-Esteem, Life Satisfaction, and Optimism) is highly associated with greater relative activation of right-precuneus in the parietal lobe. All of this work probes the nature of the oscillatory processes underlying memory and cognitive processes including co¬variation of individual differences and personality traits. The implications of these findings for our understanding of basic cognitive processes and personality dispositions are discussed.
