Method and concepts of brain oscillations pervade the neuroscience literature, especially in
cognitive processes. Electrophysiological changes in patients with cognitive impairment will …

AIM OF THE REPORT: In the companion report (Başar, this volume), the physiological
fundaments of alpha activity in integrative brain function are described. The present report is …

In this chapter, empirical wavelet transformation is used to decompose the highly
nonstationary electroencephalogram signals into modes in a Fourier spectrum. Linear and …

Gamma (γ) oscillations (30–50Hz) elicited during working memory (WM) are altered in
schizophrenia (SCZ). However, the nature of the relationship between evoked frontal …

Cognitive workload assessment plays an important role to examine the mental status of
brain for emergency situations faced by air traffic controllers, military personals and many …

Working memory (WM) deficits constitute a core symptom of schizophrenia. Inadequacy of
WM maintenance in schizophrenia has been reported to reflect abnormalities in the …

Objective To better understand the origins of working memory (WM) impairment in
schizophrenia we investigated cortical oscillatory activity in people with schizophrenia (PSZ) …

In this study we used magnetoencephalography during a modified version of the Sternberg's
memory recognition task performed by patients with early Alzheimer's disease (AD), mild …

The cognitive dysfunction present in patients with schizophrenia is thought to be driven in
part by disorganized connections between higher-order cortical fields. Although studies …

This study investigated spectral power of neural oscillations associated with word
processing in schizophrenia. Magnetoencephalography (MEG) data were acquired from 12 …
