    • An Essay on Darwin's Theory and Bergson's Creative Evolution in the Era of NeuroQuantology 

      Başar, Erol; Güntekin, Bahar (Anka Publisher, 116-11 Sok No.10 K 2 D 2, Bornova, Izmir 35050, Turkey, 2009)
      Charles Darwins's evolution theory was surveyed and analyzed by Henri Bergson in his book "Evolution Creatrice" (1907). Bergson described the importance of "intuition" and "cognitive processes" during evolution. The present ...
    • 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 ...
    • 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 ...
    • Evoked And Event Related Coherence Of Alzheimer Patients Manifest Differentiation Of Sensory-Cognitive Networks 

      Başar, Erol; Güntekin, Bahar; Tülay, Elif; Yener, Görsev G. (Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2010-10-21)
      In previous studies on Alzheimer's patients it was shown that, in frontal and parietal locations, delta and theta responses of AD patients were greatly reduced. The present study analyzed coherence functions in these highly ...
    • Increased frontal phase-locking of event-related theta oscillations in Alzheimer patients treated with cholinesterase inhibitors 

      Yener, Görsev G.; Güntekin, Bahar; Öniz, Adile; Başar, Erol (ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2007-04)
      This is a pilot study describing event-related oscillations in patients with Alzheimer-type dementia (AD). Theta responses of 22 mild probable AD subjects according to NINCDS-ADRDA criteria (11 non-treated, 11 treated by ...
    • 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. ...
    • S-Matrix and Feynman Space-Time Diagrams to Quantum Brain Approach An Extended Proposal 

      Başar, Erol (Anka Publisher, 116-11 Sok No.10 K 2 D 2, Bornova, Izmir 35050, Turkey, 2009)
      This report describes the importance of oscillations in brain function and introduces metaphors to quantum dynamics. In order to analyze scattering processes at the level of elementary particles Werner Heisenberg proposed ...
    • Sensory Evoked And Event Related Oscillations In Alzheimer's Disease: A Short Review 

      Yener, Görsev G.; Başar, Erol (Springer, Van Godewijckstraat 30, 3311 Gz Dordrecht, Netherlands, 2010)
      Diagnosis and treatment of Alzheimer's disease (AD) depend on clinical evaluation and there is a strong need for an objective tool as a biomarker. Our group has investigated brain oscillatory responses in a small group of ...
    • Surface Flux Evolution Constraints For Flux Transport Dynamos 

      Işık, Emre; Cameron, R. H.; Schmitt, D.; Jiang, J. (Edp Sciences S A, 17, Ave Du Hoggar, Pa Courtaboeuf, Bp 112, F-91944 Les Ulis Cedex A, France, 2012-06)
      The surface flux transport (SFT) model of solar magnetic fields involves empirically well-constrained velocity and magnetic fields. The basic evolution of the Sun's large-scale surface magnetic field is well described by ...
    • Why The Concept Of "Quantum Brain" Was Not Discovered In 1940s 

      Başar, Erol (Anka Publisher, 116-11 Sok No.10 K 2 D 2, Bornova, Izmir 35050, Turkey, 2010)
      Already in 1940s several neurophysiologic, biochemical and physical discoveries took place and the conjecture was open for the initiation of the "Quantum Brain Concept". The present essay explains the ensemble of discoveries ...
