tDCS individual response variability in cognitive performance

Link – An integrative clustering approach to tDCS individual response variability in cognitive performance: beyond a null effect on working memory. Abstract Despite the growing interest in the use of transcranial direct current stimulation (tDCS) for the modulation of human cognitive function, there are contradictory findings regarding the cognitive benefits of this technique. Inter-individual response […]

Autonomic/Central Coupling Benefits Working Memory

Link – Autonomic/Central Coupling Benefits Working Memory in Healthy Young Adults. Abstract Working memory (WM) is an executive function that can improve with training. However, the precise mechanism for this improvement is not known. Studies have shown greater WM gains after a period of sleep than a similar period of wake (Kuriyama et al. 2008a; […]

Is It Possible to Improve Working Memory With Prefrontal tDCS?

Link – Is It Possible to Improve Working Memory With Prefrontal tDCS? Bridging Currents to Working Memory Models. Abstract A great deal of research has been performed with the promise of improving such critical cognitive functions as working memory (WM), with transcranial direct current stimulation (tDCS), a well-tolerated, inexpensive, easy-to-use intervention. Under the assumption that […]

Effects of tDCS on working memory performance in healthy participants.

Link – Effects of 1 mA and 2 mA transcranial direct current stimulation on working memory performance in healthy participants. Abstract Anodal transcranial current stimulation (tDCS) to the left dorsolateral prefrontal cortex (DLPFC) has been shown to enhance working memory (WM) in neuropsychiatric patients. In healthy populations, however, tDCS obtains inconclusive results, mostly due to […]

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 […]
