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 ... -

Decrease of Long Distance Gamma (28-48 Hz) Coherence in Euthymic Drug Free Bipolar Patients upon Cognitive Load
Özerdem, Ayşegül; Güntekin, Bahar; Atagün, Murat İlhan; Turp, Bilge; Oral, Esat Timuçin; Başar, Erol (Elsevier Science Inc, 360 Park Ave South, New York, Ny 10010-1710 USA, 2010-05-01) -
Decrease of Theta Response in Euthymic Bipolar Patients During an Oddball Paradigm
Başar, Erol; Atagün, Murat İlhan; Güntekin, Bahar; Özerdem, Ayşegül; Tülay, Emine Elif (Springer, Van Godewijckstraat 30, 3311 Gz Dordrecht, Netherlands, 2013-06)Theta oscillations are related to cognitive functions and reflect functional integration of frontal and medial temporal structures into coherent neurocognitive networks. This study assessed event-related theta oscillations ... -
Evoked and Event Related Theta Oscillations are Decreased in Drug-Free Euthymic Bipolar Patients
