tVNS Improves High-Confidence Recognition Memory

Link – Transcutaneous Vagus Nerve Stimulation (tVNS) Improves High-Confidence Recognition Memory but Not Emotional Word Processing. Abstract Previous clinical research found that invasive vagus nerve stimulation (VNS) enhanced word recognition memory in epileptic patients, an effect assumed to be related to the activation of brainstem arousal systems. In this study, we applied non-invasive transcutaneous auricular […]

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 […]

Stimulating the Sleeping Brain.

Link – Stimulating the sleeping brain: Current approaches to modulating memory-related sleep physiology. Abstract BACKGROUND: One of the most audacious proposals throughout the history of psychology was the potential ability to learn while we sleep. The idea penetrated culture via sci-fi movies and inspired the invention of devices that claimed to teach foreign languages, facts, […]

tRNS is More Effective than tDCS for Enhancing Working Memory

Link – Transcranial Random Noise Stimulation is More Effective than Transcranial Direct Current Stimulation for Enhancing Working Memory in Healthy Individuals: Behavioural and Electrophysiological Evidence. Abstract BACKGROUND: Transcranial direct current stimulation (tDCS) has been shown to improve working memory (WM) performance in healthy individuals, however effects tend to be modest and variable. Transcranial random noise […]

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 […]

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, […]

Boosting Slow Oscillations during Sleep

Link – Boosting Slow Oscillations during Sleep to Improve Memory Function in Elderly People: A Review of the Literature. Abstract Sleep represents a crucial time window for the consolidation of memory traces. In this view, some brain rhythms play a pivotal role, first of all the sleep slow waves. In particular, the neocortical slow oscillations […]

tDCS Decreases Total Sleep Without Disturbing Memory Consolidation.

Link – Offline Bi-Frontal Anodal Transcranial Direct Current Stimulation Decreases Total Sleep Time Without Disturbing Overnight Memory Consolidation. Abstract OBJECTIVES: A proposed replay of memory traces between the hippocampus and frontal cortical brain areas during sleep is of high relevance for overnight memory consolidation. Recently, we demonstrated that bi-frontal anodal transcranial direct current stimulation (tDCS) […]

Encoding strategy mediates the effect of tDCS

Link – Encoding strategy mediates the effect of electrical stimulation over posterior parietal cortex on visual short-term memory. Abstract Over past decades, converging neuroimaging and electrophysiological findings have suggested a crucial role of posterior parietal cortex (PPC) in supporting the storage capacity of visual short-term memory (VSTM). Moreover, a few recent studies have shown that […]
