Differences in prefrontal cortex activity using near-infrared spectroscopy.

Link – Differences in prefrontal cortex activity based on difficulty in a working memory task using near-infrared spectroscopy. Abstract The Prefrontal cortex (PFC) has been highly related to executive functions such as working memory (WM). This study assesses the activity of the PFC in performing the Sternberg WM task (ST) with three levels of difficulty […]

Evidence of dissociation between working memory and attention.

Link – Behavioral and electrophysiological evidence for a dissociation between working memory capacity and feature-based attention. Abstract When attending to visual objects with particular features, neural processing is typically biased toward those features. Previous work has suggested that maintaining such feature-based attentional sets may involve the same neural resources as visual working memory. If so, […]

Effects of tDCS Duration in Older Adults.

Link – Optimising Cognitive Enhancement: Systematic Assessment of the Effects of tDCS Duration in Older Adults. Abstract Transcranial direct current stimulation (tDCS) has been shown to support cognition and brain function in older adults. However, there is an absence of research specifically designed to determine optimal stimulation protocols, and much of what is known about […]

Reactivation of Previous Experiences in a Working Memory Task.

Link – Reactivation of Previous Experiences in a Working Memory Task. Abstract Recent experiences influence the processing of new information even when those experiences are irrelevant to the current task. Does this reflect the indirect effects of a passively maintained representation of the previous experience, or is this representation reactivated when a new event occurs? […]

tDCS Hemodynamics During a Spatial Working Memory Task.

Link – Effects of Transcranial Direct Current Stimulation on Baseline and Slope of Prefrontal Cortex Hemodynamics During a Spatial Working Memory Task. Abstract Background: Transcranial direct current stimulation (tDCS) has been shown to be an inexpensive, safe, and effective way of augmenting a variety of cognitive abilities. Relatively recent advances in neuroimaging technology have provided […]

Effects of Age and Bilingualism on Working Memory

Link – ERP measures of the effects of age and bilingualism on working memory performance. Abstract Previous research has suggested that bilinguals may exhibit cognitive advantages over those who are monolingual, although conflicting results have been reported. This advantage may be heightened in older adults, because of age-related cognitive decline. However, the effects of bilingualism […]

Parietal low beta rhythm provides a working memory buffer.

Link – Parietal low beta rhythm provides a dynamical substrate for a working memory buffer. Abstract Working memory (WM) is a component of the brain’s memory systems vital for interpretation of sequential sensory inputs and consequent decision making. Anatomically, WM is highly distributed over the prefrontal cortex (PFC) and the parietal cortex (PC). Here we […]

Working memory performance with online-tDCS in schizophrenia

Link – Working memory performance with online-tDCS in schizophrenia: A randomized, double-blinded, sham-controlled, partial cross-over proof-of-concept study. Abstract Combining cognitive retraining with transcranial direct current stimulation (tDCS) has been hypothesized to improve cognitive deficits in schizophrenia. The effect of combining a neuropsychological/psychophysiological task with tDCS, called “online-tDCS” for cognitive enhancement in schizophrenia is not rigorously […]

tDCS + Cognitive Training

Link – Effects of Transcranial Direct Current Stimulation Paired With Cognitive Training on Functional Connectivity of the Working Memory Network in Older Adults. Front Aging Neurosci. 2019;11:340 Authors: Nissim NR, O’Shea A, Indahlastari A, Kraft JN, von Mering O, Aksu S, Porges E, Cohen R, Woods AJ Abstract Background: Working memory, a fundamental short-term cognitive […]
