(Elsevier Science Inc, 360 Park Ave South, New York, Ny 10010-1710 USA, 2015-02)

Occipital sources of resting-state electroencephalographic (EEG) alpha rhythms are abnormal, at the group level, in patients with amnesic mild cognitive impairment (MCI) and Alzheimer's disease (AD). Here, we evaluated the ...

Oscillations in "brain-body-mind"-A holistic view including the autonomous system

Başar, Erol (ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2008-10-15)

Studies related to brain oscillations pervade the neuroscience literature. Functional correlates of oscillations in the delta, theta, alpha, beta and gamma frequency windows are interpreted in several ways. However, only ...

Tuna, Gamze; Yener, Görsev G.; Kırkalı, Fatoş Güldal (Wiley, 111 River St, Hoboken 07030-5774, NJ USA, 2017-09)

Patients with Mild Cognitive Impairment Display Reduced Auditory Event-Related Delta Oscillatory Responses

Kurt, Pınar; Emek Savaş, Derya Durusu; Batum, Kübra; Turp, Bilge; Güntekin, Bahar; Karşıdağ, Sibel; Yener, Görsev (Hindawi Publishing Corporation, 410 Park Avenue, 15Th Floor, #287 Pmb, New York, Ny 10022 Usa, 2014)

Background. Event-related oscillations (ERO) may provide a useful tool for the identification of cognitive deficits in mild cognitive impairment (MCI) and Alzheimer's disease (AD). In the present study, we investigate ...

Depression in the elderly is associated with increased morbidity and mortality. The purpose of this study was to determine the prevalence and risk factors of depression among community-dwelling older population in an urban ...

Principles of Oscillatory Brain Dynamics and a Treatise of recognition of Faces and Facial Expressions

Başar, Erol; Güntekin, Bahar; Öniz, Adile (ELSEVIER SCIENCE BV, SARA BURGERHARTSTRAAT 25, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2006)

The research of event-related oscillations is one of fast-growing fields in neuroscience. In this study, a theory of the "whole-brain-work," which can be useful for functional interpretation of brain oscillations, is ...

Prolongation Of Alpha Oscillations İn Auditory Oddball Paradigm

Öniz, Adile; Başar, Erol (Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2009-03)
