    • A New Interpretation Of P300 Responses Upon Analysis Of Coherences 

      Güntekin, Bahar; Başar, Erol (Springer, Van Godewijckstraat 30, 3311 Gz Dordrecht, Netherlands, 2010-06)
      Previous studies on cognitive dynamics showed that oscillatory responses of P300 are composed of mainly delta and theta responses. In the present study, for the first time, the long-distance intra-hemispheric event related ...
    • A Review Of Alpha Activity İn İntegrative 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 ...
    • Brain oscillatory responses in patients with bipolar disorder manic episode before and after valproate treatment 

      Özerdem, Ayşegül; Güntekin, Bahar; Tunca, Zeliha; Başar, Erol (ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2008-10-15)
      Background: GABA/Glutamatergic dysfunction and neural circuits which regulate cognitive processing are involved in the underlying pathology of bipolar disorder. Event related oscillatory neuroelectrical activity reflects ...
    • Event-related delta oscillatory responses of Alzheimer patients 

      Yener, Görsev; Güntekin, Bahar; Başar, Erol (WILEY-BLACKWELL, COMMERCE PLACE, 350 MAIN ST, MALDEN 02148, MA USA, 2008-06)
      Background and purpose: Alzheimer type of dementia (AD) is the most common neuropsychiatric morbidity in elderly individuals. Event-related oscillations (ERO) provide an useful tool for detecting subtle abnormalities of ...
    • Prolongation Of Alpha Oscillations İn Auditory Oddball Paradigm 

      Öniz, Adile; Başar, Erol (Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2009-03)
      Although an important component of the P300 target response is the "prolonged alpha response". no relevant analysis is found in the literature. The present study emphasizes the relevance of prolongation of alpha responses ...
