      Güntekin, Bahar; Başar, Erol (Pergamon-Elsevier Science Ltd, The Boulevard, Langford Lane, Kidlington, Oxford Ox5 1Gb, England, 2014-05)
      The differentiation of faces, facial expressions and affective pictures involves processes of higher mental activity that have considerable applications in the psychology of moods and emotions. At present, the search for ...
    • 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 ...
    • Brain Oscillations Differentiate the Picture of One's Own Grandmother 

      Başar, Erol; Özgören, Murat; Öniz, Adile; Schmiedt, Christina; Başar-Eroğlu, Canan (ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2007-04)
      The present report introduces, as a first study, the concept and methods of oscillatory brain dynamics to analyze well-known (familiar) and unfamiliar face processing in the 800 ms following a face presentation. We analyzed ...
    • Brain Oscillations Evoked by the Face of a Loved Person 

      Başar, Erol; Schmiedt-Fehr, Christina; Öniz, Adile; Başar Eroğlu, Canan (ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2008-06-12)
      Previous studies have shown a close interrelation between emotional processing and memory processes using facial stimuli and applying the concept of oscillatory brain dynamics. Amending prior findings the influence of ...
    • CDK inhibitors-induced SSAT expression requires NF kappa B and PPAR gamma in MCF-7 breast cancer cells 

      Obakan Yerlikaya, Pınar; Yıldırım, Şeyma; Öztürk, Mert Burak; Berrak, Özge; Çoker Gürkan, Ajda; Arısan, Elif Damla; Ünsal Palavan, Zeynep Narçın (TUBİTAK Scientific & Technical Research Council Turkey, Ataturk Bulvarı No 221, Kavaklıdere, Ankara, 00000, Turkey, 2015)
      The cyclin-dependent kinase (CDK) inhibitors purvalanol and roscovitine are therapeutic agents that control cell proliferation through regulating cell-cycle machinery. They also affect polyamine (PA) metabolism, which is ...
    • Emotional Face Expressions are Differentiated With Brain Oscillations 

      Güntekin, Bahar; Başar, Erol (ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2007-04)
      The differentiation of "facial expressions" is a process of higher mental activity, which has considerable applications in "psychology of moods and emotions". We applied the approach of event-related oscillations (EROs) ...
    • Event related desynchronization: use as a neurophysiologic marker is restricted 

      Başar, Erol; Turp Gölbaşı, Bilge (Springer, Van Godewijckstraat 30, 3311 Gz Dordrecht, Netherlands, 2014-12)
      The present research aims to show that the occurrence of alpha blocking or event-related desynchronization (ERD) strongly depends on the amplitude and also on the phase angle of alpha activity at the stimulus onset. Simple ...
    • Oscillations in "brain-body-mind"-A holistic view including the autonomous system 

      Başar, Erol (ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2008-10-15)
      Studies related to brain oscillations pervade the neuroscience literature. Functional correlates of oscillations in the delta, theta, alpha, beta and gamma frequency windows are interpreted in several ways. However, only ...
    • Principles of Oscillatory Brain Dynamics and a Treatise of recognition of Faces and Facial Expressions
