    • 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 ...
    • Decrease of Event Related Delta Oscillations in Euthymic Patients with Bipolar Disorder 

      Başar, Erol; Atagün, Murat İlhan; Güntekin, Bahar; Masali, Belinda; Tülay, Emine Elif (Elsevier Science Inc, 360 Park Ave South, New York, Ny 10010-1710 USA, 2013-05-01)
      Decreased delta oscillation upon cognitive load is common in patients with Alzheimer׳s disease, mild cognitive impairment, and schizophrenia. However, there is no previous study analyzing the delta responses in euthymic ...
    • 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 ...
    • 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. ...
