    • A Review of Brain Oscillations in Perception of Faces and Emotional Pictures 

      Güntekin, Bahar; Başar, Erol (Pergamon-Elsevier Science Ltd, The Boulevard, Langford Lane, Kidlington, Oxford Ox5 1Gb, England, 2014-05)
      The differentiation of faces, facial expressions and affective pictures involves processes of higher mental activity that have considerable applications in the psychology of moods and emotions. At present, the search for ...
    • 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 ...
    • 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 ...
    • 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 ...
    • Decrease of Delta Oscillatory Responses in Cognitively Normal Parkinson's Disease 

      Emek Savaş, Derya Durusu; Ozmus, Guelin; Güntekin, Bahar; Dönmez Çolakoğlu, Berril; Çakmur, Raif; Başar, Erol; Yener, Görsev G. (Sage Publications Inc, 2455 Teller Rd, Thousand Oaks, Ca 91320 USA, 2017-09)
      Parkinson's disease (PD) is a common progressive neurodegenerative disorder. This study aims to compare sensory-evoked oscillations (SEOs) and event-related oscillations (EROs) of visual modality in cognitively normal PD ...
    • Decrease of delta oscillatory responses is associated with increased age in healthy elderly 

      Emek Savaş, Derya Durusu; Güntekin, Bahar; Yener, Görsev G.; Başar, Erol (Elsevier Science Bv, Po Box 211, 1000 AE Amsterdam, Netherlands, 2016-05)
      Background: The purpose of this study was to investigate changes in delta event-related oscillations (EROs) in younger and older healthy elderly subjects. We hypothesized that delta EROs were affected by age-related changes, ...
    • 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 ...
    • Increased Beta Frequency (15-30 Hz) Oscillatory Responses in Euthymic Bipolar Patients Under Lithium Monotherapy 

      Tan, Devran; Özerdem, Ayşegül; Güntekin, Bahar; Atagün, Murat İlhan; Tülay, Elif; Karadağ, Figen; Başar, Erol (Sage Publications Inc, 2455 Teller Rd, Thousand Oaks, Ca 91320 USA, 2016-04)
      The effect of lithium on neurocognition is not still fully explored. Brain oscillatory activity is altered in bipolar disorder. We aimed to assess the oscillatory responses of euthymic bipolar patients and how they are ...
