    • A comparative analysis of sensory visual evoked oscillations with visual cognitive event related oscillations in Alzheimer's disease 

      Yener, Görsev G.; Güntekin, Bahar; Tülay, Elif; Başar, Erol (ELSEVIER IRELAND LTD, ELSEVIER HOUSE, BROOKVALE PLAZA, EAST PARK SHANNON, CO, CLARE, 00000, IRELAND, 2009-09-25)
      We compared visual evoked oscillatory responses of subjects with Alzheimer's disease (AD) (n = 22) to healthy elderly controls (n = 19) elicited by simple light stimuli. The visual evoked oscillatory responses in AD subjects ...
    • 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 brain oscillations in cognitive disorders and the role of neurotransmitters 

      Başar, Erol; Güntekin, Bahar (ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2008-10-15)
      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 ...
    • Cognitive Impairment in Parkinson's Disease Is Reflected with Gradual Decrease of EEG Delta Responses during Auditory Discrimination 

      Güntekin, Bahar; Hanoğlu, Lütfü; Güner, Dilan; Helvacı Yılmaz, Nesrin; Çadırcı, Fadime; Mantar, Nagihan; Aktürk, Tuba; Emek Savaş, Derya Durusu; Özer, Fahriye Feriha; Yener, Görsev G.; Başar, Erol (Frontiers Media Sa, Avenue Du Tribunal Federal 34, Lausanne, Ch-1015, Switzerland, 2018-02-21)
      Parkinson's disease (PD) is a neurodegenerative disease that is characterized by loss of dopaminergic neurons in the substantia nigra. Mild Cognitive impairment (MCI) and dementia may come along with the disease. New ...
    • 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 ...
