  • Modulating dream experience: Noninvasive brain stimulation over the sensorimotor cortex reduces dream movement.
    Related ArticlesModulating dream experience: Noninvasive brain stimulation over the sensorimotor cortex reduces dream movement. Sci Rep. 2020 04 21;10(1):6735 Authors: Noreika V, Windt JM, Kern M, Valli K, Salonen T, Parkkola R, Revonsuo A, Karim AA, Ball T, Lenggenhager B Abstract Recently, cortical correlates of specific dream contents have been reported, such as the activation of the sensorimotor cortex during dreamed hand clenching. Yet, despite a close resemblance of such activation patterns to those seen during the corresponding wakeful behaviour, the causal mechanisms underlying specific dream contents remain largely elusive. Here, we aimed to investigate the causal role ... read more

  • Transcranial direct current stimulation (tDCS) over vmPFC modulates interactions between reward and emotion in delay discounting.
    Related ArticlesTranscranial direct current stimulation (tDCS) over vmPFC modulates interactions between reward and emotion in delay discounting. Sci Rep. 2019 12 10;9(1):18735 Authors: Manuel AL, Murray NWG, Piguet O Abstract Delay discounting requires computing trade-offs between immediate-small rewards and later-larger rewards. Negative and positive emotions shift decisions towards more or less impulsive responses, respectively. Models have conceptualized this trade-off by describing an interplay between "emotional" and "rational" processes, with the former involved during immediate choices and relying on the ventromedial prefrontal cortex (vmPFC), and the latter involved in long-term choices and relying on the dorsolateral prefrontal cortex (dlPFC). ... read more

Eur J Neurosci. 2020 Nov 21;: Authors: Boayue NM, Csifcsák G, Kreis IV, Schmidt C, Finn I, Hovde Vollsund AE, Mittner M Abstract While the involvement of executive processes in mind wandering is largely undebated, their exact relationship is subject to an ongoing debate and rarely studied dynamically within-subject. Several brain-stimulation studies using transcranial direct current stimulation (tDCS) have attempted to modulate mind-wandering propensity by stimulating the left dorsolateral prefrontal cortex (DLPFC) which is an important hub in the prefrontal control ... read more

  • Transcutaneous vagus nerve stimulation in humans induces pupil dilation and attenuates alpha oscillations.
    Related ArticlesTranscutaneous vagus nerve stimulation in humans induces pupil dilation and attenuates alpha oscillations. J Neurosci. 2020 Nov 18;: Authors: Sharon O, Fahoum F, Nir Y Abstract Vagus nerve stimulation (VNS) is widely used to treat drug-resistant epilepsy and depression. While the precise mechanisms mediating its long-term therapeutic effects are not fully resolved, they likely involve locus coeruleus (LC) stimulation via the nucleus of the solitary tract (NTS), which receives afferent vagal inputs. In rats, VNS elevates LC firing and forebrain noradrenaline levels, whereas LC lesions suppress VNS therapeutic efficacy. Non-invasive transcutaneous VNS (tVNS) employs electrical stimulation that targets the ... read more

J Neuropsychol. 2020 Nov 18;: Authors: Firouzi M, Van Herk K, Kerckhofs E, Swinnen E, Baeken C, Van Overwalle F, Deroost N Abstract Implicit motor sequence learning (IMSL) is affected in Parkinson's disease (PD). Research in healthy young participants shows the potential for transcranial direct-current stimulation (tDCS) over the primary motor cortex (M1) to enhance IMSL. In PD, only null effects have been reported to date. We determined concurrent, short-term, and long-term effects of anodal tDCS over M1 on IMSL, as measured ... read more

IEEE Trans Neural Syst Rehabil Eng. 2020 01;28(1):23-31 Authors: Kadir S, Kaza C, Weissbart H, Reichenbach T Abstract Neural activity tracks the envelope of a speech signal at latencies from 50 ms to 300 ms. Modulating this neural tracking through transcranial alternating current stimulation influences speech comprehension. Two important variables that can affect this modulation are the latency and the phase of the stimulation with respect to the sound. While previous studies have found an influence of both variables on speech comprehension, the interaction ... read more

  • A causal role for the right angular gyrus in self-location mediated perspective taking.
    Related ArticlesA causal role for the right angular gyrus in self-location mediated perspective taking. Sci Rep. 2020 Nov 05;10(1):19229 Authors: de Boer DML, Johnston PJ, Kerr G, Meinzer M, Cleeremans A Abstract Recent theories suggest that self-consciousness, in its most elementary form, is functionally disconnected from the phenomenal body. Patients with psychosis frequently misattribute their thoughts and actions to external sources; and in certain out-of-body experiences, lucid states, and dreams body-ownership is absent but self-identification is preserved. To explain these unusual experiences, we hypothesized that self-identification depends on inferring self-location at the right angular gyrus (i.e., perspective-taking). This process relates ... read more

  • Excitatory and inhibitory lateral interactions effects on contrast detection are modulated by tRNS.

Sci Rep. 2019 12 17;9(1):19274 Authors: Battaglini L, Contemori G, Fertonani A, Miniussi C, Coccaro A, Casco C Abstract Contrast sensitivity for a Gabor signal is affected by collinear high-contrast Gabor flankers. The flankers reduce (inhibitory effect) or increase (facilitatory effect) sensitivity, at short (2λ) and intermediate (6λ) target-to-flanker separation respectively. We investigated whether these inhibitory/facilitatory sensitivity effects are modulated by transcranial random noise stimulation (tRNS) applied to the occipital and frontal cortex of human observers during task performance. Signal detection theory was ... read more

PLoS One. 2020;15(9):e0239125 Authors: Medvedeva TM, Sysoeva MV, Lüttjohann A, van Luijtelaar G, Sysoev IV Abstract A mesoscale network model is proposed for the development of spike and wave discharges (SWDs) in the cortico-thalamo-cortical (C-T-C) circuit. It is based on experimental findings in two genetic models of childhood absence epilepsy-rats of WAG/Rij and GAERS strains. The model is organized hierarchically into two levels (brain structures and individual neurons) and composed of compartments for representation of somatosensory cortex, reticular and ventroposteriomedial thalamic nuclei.

    Related ArticlesEnhancing Motor Brain Activity Improves Memory for Action Language: A tDCS Study. Cereb Cortex. 2020 Nov 02;: Authors: Vitale F, Padrón I, Avenanti A, de Vega M Abstract The embodied cognition approach to linguistic meaning posits that action language understanding is grounded in sensory-motor systems. However, evidence that the human motor cortex is necessary for action language memory is meager. To address this issue, in two groups of healthy individuals, we perturbed the left primary motor cortex (M1) by means of either anodal or cathodal transcranial direct current stimulation (tDCS), before participants had to memorize lists of manual action ... read more

Sci Rep. 2019 07 29;9(1):10950 Authors: Sdoia S, Conversi D, Pecchinenda A, Ferlazzo F Abstract Adaptive behaviour requires the ability to process goal-relevant events at the expense of irrelevant ones. However, perception of a relevant visual event can transiently preclude access to consciousness of subsequent events - a phenomenon called attentional blink (AB). Here we investigated involvement of the left dorsolateral prefrontal cortex (DLPFC) in conscious access, by using transcranial direct current stimulation (tDCS) to potentiate ... read more
