    • A review of alpha activity in integrative brain function: Fundamental physiology, Sensory coding, cognition and pathology 

      Başar, Erol (Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2012-10)
      Aim of the review: Questions related to the genesis and functional correlates of the brain's alpha oscillations around 10 Hz (Alpha) are one of the fundamental research areas in neuroscience. In recent decades, analysis ...
    • A short review of alpha activity In cognitive processes and in cognitive impairment 

      Başar, Erol; Güntekin, Bahar (Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2012-10)
      Aim of the report: In the companion report (Basar, this volume), the physiological fundaments of alpha activity in integrative brain function are described. The present report is a review of the significant role of alpha ...
    • Event Related Oscillations in Euthymic Patients With Bipolar Disorder 

      Özerdem, Ayşegül; Kocaaslan, Sibel; Tunca, Zeliha; Başar, Erol (ELSEVIER IRELAND LTD, ELSEVIER HOUSE, BROOKVALE PLAZA, EAST PARK SHANNON, CO, CLARE, 00000, IRELAND, 2008-10-17)
      Bipolar disorder involves dysfunction in gamma amino butyric acid (GABA)/glutamatergic systems and neural circuits that regulate cognitive processing. Valproate, a mood stabilizing anticonvulsant, modulates GABA/glutamate ...
    • Facial Affect Manifested By Multiple Oscillations 

      Güntekin, Bahar; Başar, Erol (Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2009-01)
      The present study describes electrophysiological differentiation of "Facial Expressions" by using the method of event-related oscillations (EROS). These measures were used to assess electrical manifestations of emotional ...
    • Gender Differences Influence Brain's Beta Oscillatory Responses in Recognition of Facial Expressions 

      Güntekin, Bahar; Başar, Erol (ELSEVIER IRELAND LTD, ELSEVIER HOUSE, BROOKVALE PLAZA, EAST PARK SHANNON, CO, CLARE, 00000, IRELAND, 2007-09-07)
      There are only few studies describing gender differences in recognition of facial expressions. Our study has the aim to analyze the effect of gender differences in oscillatory brain responses. Three sets of Ekman and ...
    • Principles of Oscillatory Brain Dynamics and a Treatise of recognition of Faces and Facial Expressions 

      Başar, Erol; Güntekin, Bahar; Öniz, Adile (ELSEVIER SCIENCE BV, SARA BURGERHARTSTRAAT 25, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2006)
      The research of event-related oscillations is one of fast-growing fields in neuroscience. In this study, a theory of the "whole-brain-work," which can be useful for functional interpretation of brain oscillations, is ...
    • Reduced long distance gamma (28-48 Hz) coherence in euthymic patients with bipolar disorder 

      Özerdem, Ayşegül; Güntekin, Bahar; Atagün, İlhan; Turp, Bilge; Başar, Erol (Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2011-08)
      Background: EEG coherence represents the brain's functional connectivity. Synchronous neural gamma oscillations are critical for cortico-cortical communication and large-scale integration of distributed sets of neurons. ...
