چکیده

It has been claimed that the coordination of neuronal oscillations differing in frequency is relevant for cognition. However, the validity of this claim has scarcely been investigated. Recent studies revealed that cross-frequency phase coupling and modulations of alpha-power dissociate between retention of relevant and suppression of irrelevant information in visual working memory (WM). We summarize these important results, and discuss possible implications for understanding the neural mechanisms of WM constraints.

Brain Oscillatory Correlates of Altered Executive Functioning in Positive and Negative Symptomatic Schizophrenia Patients and Healthy Controls

Working Memory and executive functioning deficits are core characteristics of patients suffering from schizophrenia. Electrophysiological research indicates that altered patterns of neural oscillatory mechanisms underpinning executive functioning are associated with the psychiatric disorder. Such brain oscillatory changes have been found in local amplitude differences at gamma and theta frequen...

Oscillatory correlates of interference 1 Running head: OSCILLATORY CORRELATES OF INTERFERENCE Distinct electrophysiological correlates of proactive and similarity-based interference in visual working memory

Using scalp electroencephalography, we investigated the oscillatory correlates of similarity-based and proactive interference in a visual working memory task. On each trial, participants were asked to judge whether a face or a sinusoidal grating was present on a just-studied list. Similarity-based interference occurs due to the similarity of study items to the probe and to one another, whereas ...

The Effect of Cognitive Rehabilitation on improving the working memory of adolescents with Brain damage

Abstract The aim of this study was to evaluate the effectiveness of cognitive rehabilitation on improving working memory of adolescents with traumatic brain injury. The method of this research was quasi-experimental pre-test-post-test with control and follow-up groups. To conduct this study, 20 adolescents aged 9-18 years with traumatic brain injury referred to medical centers in S...

Brain Functional Correlates of Intelligence Score in ADHD Based on EEG

Introduction: It has been shown that intelligence as a general mental ability is related to the structure and function of the brain regions. However, the specificity of these regional dependencies to the intelligence scores in the typical and atypical developed individuals needs to be well understood. In this study, we hypothesized that neural correlates of IQ should not have a fixed pattern ra...
