    Related ArticlesVisuospatial Neglect - a Theory-Informed Overview of Current and Emerging Strategies and a Systematic Review on the Therapeutic Use of Non-invasive Brain Stimulation. Neuropsychol Rev. 2019 12;29(4):397-420 Authors: Zebhauser PT, Vernet M, Unterburger E, Brem AK Abstract Visuospatial neglect constitutes a supramodal cognitive deficit characterized by reduction or loss of spatial awareness for the contralesional space. It occurs in over 40% of right- and 20% of left-brain-lesioned stroke patients with lesions located mostly in parietal, frontal and subcortical brain areas. Visuospatial neglect is a multifaceted syndrome - symptoms can be divided into sensory, motor and representational neglect ... read more

  • Electrifying discourse: Anodal tDCS of the primary motor cortex selectively reduces action appraisal in naturalistic narratives.
    Electrifying discourse: Anodal tDCS of the primary motor cortex selectively reduces action appraisal in naturalistic narratives. Cortex. 2020 Aug 25;: Authors: Birba A, Vitale F, Padrón I, Dottori M, de Vega M, Zimerman M, Sedeño L, Ibáñez A, García AM Abstract Non-invasive stimulation of the primary motor cortex (M1) modulates processing of decontextualized action words and sentences (i.e., verbal units denoting bodily motion). This suggests that language comprehension hinges on brain circuits mediating the bodily experiences evoked by verbal material. Yet, despite its relevance to constrain mechanistic language models, such a finding fails to reveal whether and how relevant circuits ... read more

  • Failure to Improve Verbal Fluency with Transcranial Direct Current Stimulation.
    Related ArticlesFailure to Improve Verbal Fluency with Transcranial Direct Current Stimulation. Neuroscience. 2020 Sep 15;: Authors: Klaus J, Hartwigsen G Abstract Previous studies in healthy populations have provided equivocal evidence whether the application of anodal transcranial direct current stimulation (tDCS) over the left prefrontal cortex (PFC) can improve performance in verbal fluency tasks. In this double-blind, randomised within-participant study, we investigated whether anodal tDCS over the left PFC improves verbal fluency performance relative to sham tDCS. Forty eight healthy native German speakers performed two verbal fluency tasks after having received 20 min of anodal or sham tDCS over the left PFC. ... read more

  • Stimulating the left dorsolateral prefrontal cortex improves the memory representation of threats among individuals with high avoidant attachment.
    Related ArticlesStimulating the left dorsolateral prefrontal cortex improves the memory representation of threats among individuals with high avoidant attachment. Behav Brain Res. 2019 11 05;373:112073 Authors: Zhou M, Chen X, Chen W, Bai X Abstract Prior research has suggested that individuals with high avoidant attachment may demonstrate a vigilant attentional bias and selective attentional avoidance towards attachment-related negative information (threat information). Similarly, some evidence suggests that impairment of hot working memory (WM) or emotional-related WM occurs in highly avoidant individuals. Moreover, functional MRI studies have demonstrated that the less-activated left dorsolateral prefrontal cortex (L-DLPFC) is related to the impairment ... read more

  • Looking at ancillary systems for verb recovery: Evidence from non-invasive brain stimulation.
    Related ArticlesLooking at ancillary systems for verb recovery: Evidence from non-invasive brain stimulation. Brain Cogn. 2020 03;139:105515 Authors: Pisano F, Marangolo P Abstract Several behavioural and neuroimaging studies have suggested that the language function is not restricted into the left areas but it involves regions not predicted by the classical language model. Accordingly, the Embodied Cognition theory postulates a close interaction between the language and the motor system. Indeed, it has been shown that non-invasive brain stimulation (NIBS) is effective for language recovery also when applied over sensorimotor regions, such as the motor cortex, the cerebellum and the spinal ... read more

  • Transcranial Direct Current Stimulation over the Prefrontal Cortex Alters Encoding and Judgments of Learning Based on Fluency.
    Related ArticlesTranscranial Direct Current Stimulation over the Prefrontal Cortex Alters Encoding and Judgments of Learning Based on Fluency. J Cogn Neurosci. 2019 11;31(11):1710-1725 Authors: Gaynor AM, Chua EF Abstract Past research has shown that judgments of learning (JOLs), subjective confidence judgments made at study about later memorability, are inferential in nature and based on cues available during encoding. Participants tend to use fluency as a cue and give higher JOLs to more fluently encoded items, despite having better recognition memory for disfluently encoded items, which leads to poor JOL accuracy. Research has implicated the dorsolateral prefrontal cortex (DLPFC) and anterior ... read more

Neuroimage. 2019 11 15;202:116175 Authors: Zoefel B, Davis MH, Valente G, Riecke L Abstract Research on whether perception or other processes depend on the phase of neural oscillations is rapidly gaining popularity. However, it is unknown which methods are optimally suited to evaluate the hypothesized phase effect. Using a simulation approach, we here test the ability of different methods to detect such an effect on dichotomous (e.g., "hit" vs "miss") and continuous (e.g., scalp potentials) response variables.

  • The time course of ineffective sham-blinding during low-intensity (1 mA) transcranial direct current stimulation.

Eur J Neurosci. 2019 10;50(8):3380-3388 Authors: Greinacher R, Buhôt L, Möller L, Learmonth G Abstract Studies using transcranial direct current stimulation (tDCS) typically compare an active protocol relative to a shorter sham (placebo) protocol. Both protocols are presumed to be perceptually identical on the scalp, and thus represent an effective method of delivering double-blinded experimental designs. However, participants often show above-chance accuracy when asked which condition involved active/sham retrospectively. We assessed the time course of sham-blinding during active and sham tDCS. We predicted that ... read more
