  • The critical role of cognitive-based trait differences in transcranial direct current stimulation (tDCS) suppression of food craving and eating in frank obesity.
    Related ArticlesThe critical role of cognitive-based trait differences in transcranial direct current stimulation (tDCS) suppression of food craving and eating in frank obesity. Appetite. 2017 Sep 01;116:568-574 Authors: Ray MK, Sylvester MD, Osborn L, Helms J, Turan B, Burgess EE, Boggiano MM Abstract Obesity remains a major public health concern and novel treatments are needed. Transcranial direct current stimulation (tDCS) is a neuromodulation technique shown to reduce food craving and consumption, especially when targeting the dorsolateral prefrontal cortex (DLPFC) with a right anode/left cathode electrode montage. Despite the implications to treat frank (non-bingeeating) obesity, no study has tested the ... read more

  • tDCS over left M1 or DLPFC does not improve learning of a bimanual coordination task.
    Related ArticlestDCS over left M1 or DLPFC does not improve learning of a bimanual coordination task. Sci Rep. 2016 10 25;6:35739 Authors: Vancleef K, Meesen R, Swinnen SP, Fujiyama H Abstract Previously, transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) has resulted in improved performance in simple motor tasks. For a complex bimanual movement, studies using functional magnetic resonance imaging and transcranial magnetic stimulation indicated the involvement of the left dorsolateral prefrontal cortex (DLPFC) as well as left M1. Here we investigated the relative effect of up-regulating the cortical function in left DLPFC and left ... read more

  • Low to No Effect: Application of tRNS During Two-Digit Addition.
    Related ArticlesLow to No Effect: Application of tRNS During Two-Digit Addition. Front Neurosci. 2018;12:176 Authors: Bieck SM, Artemenko C, Moeller K, Klein E Abstract Transcranial electric stimulation such as transcranial random noise stimulation (tRNS) and transcranial direct current stimulation (tDCS) have been used to investigate structure-function relationships in numerical cognition. Recently, tRNS was suggested to be more effective than tDCS. However, so far there is no evidence on the differential impact of tDCS and tRNS on numerical cognition using the same experimental paradigm. In the present study, we used a two-digit addition paradigm for which significant-albeit small-effects of tDCS were ... read more

  • Individual Differences and Long-term Consequences of tDCS-augmented Cognitive Training.
    Related ArticlesIndividual Differences and Long-term Consequences of tDCS-augmented Cognitive Training. J Cogn Neurosci. 2017 Sep;29(9):1498-1508 Authors: Katz B, Au J, Buschkuehl M, Abagis T, Zabel C, Jaeggi SM, Jonides J Abstract A great deal of interest surrounds the use of transcranial direct current stimulation (tDCS) to augment cognitive training. However, effects are inconsistent across studies, and meta-analytic evidence is mixed, especially for healthy, young adults. One major source of this inconsistency is individual differences among the participants, but these differences are rarely examined in the context of combined training/stimulation studies. In addition, it is unclear how long the effects of ... read more

    Related ArticlesAuditory System Target Engagement During Plasticity-Based Interventions in Schizophrenia: A Focus on Modulation of N-Methyl-D-Aspartate-Type Glutamate Receptor Function. Biol Psychiatry Cogn Neurosci Neuroimaging. 2018 Feb 22;: Authors: Kantrowitz JT, Swerdlow NR, Dunn W, Vinogradov S Abstract Cognitive deficits are predictive of long-term social and occupational functional deficits in schizophrenia but are currently without gold-standard treatments. In particular, augmentation of auditory cortical neuroplasticity may represent a rate-limiting first step before addressing higher-order cognitive deficits. We review the rationale for N-methyl-d-aspartate-type glutamate receptor (NMDAR) modulators as treatments for auditory plasticity deficits in schizophrenia, along with potential serum and electroencephalographic target engagement ... read more

  • THE PHYSIOLOGICAL EFFECTS OF TRANSCRANIAL ELECTRICAL STIMULATION DO NOT APPLY TO PARAMETERS COMMONLY USED IN STUDIES OF COGNITIVE NEUROMODULATION.
    THE PHYSIOLOGICAL EFFECTS OF TRANSCRANIAL ELECTRICAL STIMULATION DO NOT APPLY TO PARAMETERS COMMONLY USED IN STUDIES OF COGNITIVE NEUROMODULATION. Neuropsychologia. 2018 Apr 06;: Authors: Parkin BL, Bhandari M, Glen JC, Walsh V Abstract Transcranial direct current stimulation (tDCS) and transcranial random noise stimulation (tRNS) have been claimed to produce many remarkable enhancements in perception, cognition, learning and numerous clinical conditions. The physiological basis of the claims for tDCS rests on the finding that 1mA of unilateral anodal stimulation increases cortical excitation and 1mA of cathodal produces inhibition. Here we show that these classic excitatory and inhibitory effects do not hold ... read more

Neuroimage. 2018 Mar 29;: Authors: Winker C, Rehbein MA, Sabatinelli D, Dohn M, Maitzen J, Wolters CH, Arolt V, Junghofer M Abstract The ventromedial prefrontal cortex (vmPFC) is associated with emotional states that can be characterized as positive affect. Moreover, a variety of psychiatric disorders that are associated with disturbed reactions toward reward- or safety-signaling stimuli reveal functional or structural anomalies within this area. Thus, neuromodulation of this region via transcranial direct current stimulation (tDCS) offers an attractive opportunity to noninvasively influence pleasant emotional and reward processing. ... read more

Epilepsia Open. 2018 Mar;3(1):18-29 Authors: Chan AY, Rolston JD, Rao VR, Chang EF Abstract Epilepsy is a common, debilitating neurological disorder characterized by recurrent seizures. Mood disorders and cognitive deficits are common comorbidities in epilepsy that, like seizures, profoundly influence quality of life and can be difficult to treat. For patients with refractory epilepsy who are not candidates for resection, neurostimulation, the electrical modulation of epileptogenic brain tissue, is an emerging treatment alternative. Several forms of neurostimulation are currently available, and therapy selection hinges on relative efficacy for seizure ... read more
