      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 ...
    • Best method for analysis of brain oscillations in healthy subjects and neuropsychiatric diseases 

      Başar, Erol; Turp Gölbaşı, Bilge; Tülay, Elif; Aydın, Serap; Başar Eroğlu, Canan (Elsevier Science Bv, Po Box 211, 1000 AE Amsterdam, Netherlands, 2016-05)
      The research related to brain oscillations and their connectivity is in a new take-off trend including the applications in neuropsychiatric diseases. What is the best strategy to learn about functional correlation of ...
    • Brain's alpha activity is highly reduced in euthymic bipolar disorder patients 

      Başar, Erol; Güntekin, Bahar; Turp Gölbaşı, Bilge; Atagün, Murat İlhan; Özerdem, Ayşegül; Tülay, Elif (Springer, Van Godewijckstraat 30, 3311 Gz Dordrecht, Netherlands, 2012-02)
      Brain's alpha activity and alpha responses belong to major electrical signals that are related to sensory/cognitive signal processing. The present study aims to analyze the spontaneous alpha activity and visual evoked alpha ...
    • Event Related Oscillations in Euthymic Patients With Bipolar Disorder 

      Özerdem, Ayşegül; Kocaaslan, Sibel; Tunca, Zeliha; Başar, Erol (ELSEVIER IRELAND LTD, ELSEVIER HOUSE, BROOKVALE PLAZA, EAST PARK SHANNON, CO, CLARE, 00000, IRELAND, 2008-10-17)
      Bipolar disorder involves dysfunction in gamma amino butyric acid (GABA)/glutamatergic systems and neural circuits that regulate cognitive processing. Valproate, a mood stabilizing anticonvulsant, modulates GABA/glutamate ...
    • FT-IR spectroscopy and multivariate analysis as an auxiliary tool for diagnosis of mental disorders: Bipolar and schizophrenia cases 

      Öğrüç Ildız, Gülce; Arslan, M.; Ünsalan, Ozan; Araujo-Andrade, C.; Kurt, Ethan; Karatepe, Hasan Turan; Yılmaz, Ayberk; Bölükbaşı Yalçınkaya, Olcay; Herken, Hasan (Pergamon-Elsevier Science Ltd, The Boulevard, Langford Lane, Kidlington, Oxford Ox5 1Gb, England, 2016-01-05)
      In this study, a methodology based on Fourier-transform infrared spectroscopy and principal component analysis and partial least square methods is proposed for the analysis of blood plasma samples in order to identify ...
    • How is the brain working? Research on brain oscillations and connectivities in a new "Take-Off" state 

      Başar, Erol; Düzgün, Aysel (Elsevier Science Bv, Po Box 211, 1000 AE Amsterdam, Netherlands, 2016-05)
      The present report is a trial to survey analysis and applications of brain oscillations in cognitive impairment for opening the way to a new take off in research on brain oscillation. Although the number of papers related ...
    • Lithium excessively enhances event related beta oscillations in patients with bipolar disorder 

      Atagün, Murat İlhan; Güntekin, Bahar; Tan, Devran; Tülay, Emine Elif; Başar, Erol (Elsevier Science Bv, Po Box 211, 1000 AE Amsterdam, Netherlands, 2015-01-01)
      Background: Previous resting-state electroencephalography studies have consistently shown that lithium enhances delta and theta oscillations in default mode networks. Cognitive task based networks differ horn resting-state ...
