      The analysis of the functional correlates of "brain oscillations" has become an important branch of neuroscience. Although research on the functional correlates of brain oscillation has progressed to a high level, studies ...
    • Auditory Delta Event-related Oscillatory Responses are Decreased in Alzheimer's Disease 

      Başar, Erol; Yener, Görsev; Güntekin, Bahar; Necioğlu Örken, Dilek; Forta, H. (Ios Press, Nieuwe Hemweg 6B, 1013 Bg Amsterdam, Netherlands, 2012)
      Background: Visual delta event-related (ERO) and evoked oscillations (EO) of Alzheimer patients (AD) are different than healthy. In the present study, the analysis is extented to include auditory ERO and EO in AD. The ...
    • Beyin-Beden-Zihin Etkileşiminde "Nebulöz Kartezyen Sistem" 

      Başar, Erol; Güntekin, Bahar (İstanbul Kültür Üniversitesi Yayınları, 2006-12)
      Rene Descartes 'in gelistirdigi Kartezyen Sistem "Newton 'un Dinamik Kurallari" ile ilintili ve iç içe geçmis olan temel bir kavramsal ve analitik sistemdir. Rönesans'tan itibaren modem bilimin youlunu açmistir. 20 inci ...
    • 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 ...
    • Decrease of Alpha/Beta Ratio in EEG Activity in Drug Free Euthymic Bipolar Patients 

      Başar, Erol; Tülay, Elif; Özerdem, Ayşegül; Atagün, Murat İlhan; Güntekin, Bahar (Elsevier Science Inc, 360 Park Ave South, New York, Ny 10010-1710 Usa, 2012-04-15)
    • Disturbance In Long Distance Gamma Coherence In Bipolar Disorder 

      Özerdem, Ayşegül; Güntekin, Bahar; Saatçı, Ertuğrul; Tunca, Zeliha; Başar, Erol (Pergamon-Elsevier Science Ltd, The Boulevard, Langford Lane, Kidlington, Oxford Ox5 1Gb, England, 2010-08-16)
      The aim of this study was to investigate long distance event-related gamma (28-48 Hz) coherence in mania before and after valproate monotherapy. Gamma coherence in response to visual oddball paradigm in ten medication-free, ...
    • 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) ...
    • 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)
