  • The effects of noninvasive brain stimulation on heart rate and heart rate variability: A systematic review and meta-analysis
    J Neurosci Res. 2022 May 17. doi: 10.1002/jnr.25062. Online ahead of print.ABSTRACTNoninvasive brain stimulation (NIBS) techniques such as transcranial magnetic stimulation and transcranial direct current stimulation are widely used to test the involvement of specific cortical regions in various domains such as cognition and emotion. Despite the capability of stimulation techniques to test causal directions, this approach has been only sparsely used to examine the cortical regulation of autonomic nervous system (ANS) functions such as heart rate (HR) and heart rate variability (HRV) and to test current models in this regard. In this preregistered (PROSPERO) systematic review and meta-analysis, we ... read more

  • More focal, less heterogeneous? Multi-level meta-analysis of cathodal high-definition transcranial direct current stimulation effects on language and cognition
    J Neural Transm (Vienna). 2022 May 18. doi: 10.1007/s00702-022-02507-3. Online ahead of print.ABSTRACTHigh-definition transcranial direct current stimulation (HD-tDCS) is a relatively focal, novel non-invasive brain stimulation method with the potential to investigate the causal contributions of specific cortical brain regions to language and cognition. Studies with HD-tDCS typically employ a 4 × 1 electrode design with a single central target electrode surrounded by four return electrodes, among which return current intensity is evenly distributed. With cathodal HD-tDCS, neural excitability in the target region is assumed to be reduced, which offers interesting perspectives for neuropsychological research and interventions. This multi-level meta-analysis ... read more

  • Efficacy of Transcranial Direct-Current Stimulation in Catatonia: A Review and Case Series
    Front Psychiatry. 2022 Apr 27;13:876834. doi: 10.3389/fpsyt.2022.876834. eCollection 2022.ABSTRACTCatatonia is a severe neuropsychiatric syndrome, usually treated by benzodiazepines and electroconvulsive therapy. However, therapeutic alternatives are limited, which is particularly critical in situations of treatment resistance or when electroconvulsive therapy is not available. Transcranial direct-current stimulation (tDCS) is a promising non-invasive neuromodulatory technique that has shown efficacy in other psychiatric conditions. We present the largest case series of tDCS use in catatonia, consisting of eight patients in whom tDCS targeting the left dorsolateral prefrontal cortex and temporoparietal junction was employed. We used a General Linear Mixed Model to isolate the effect ... read more

  • Fatigue in Multiple Sclerosis: A Review of the Exploratory and Therapeutic Potential of Non-Invasive Brain Stimulation
    Front Neurol. 2022 Apr 28;13:813965. doi: 10.3389/fneur.2022.813965. eCollection 2022.ABSTRACTFatigue is the most commonly reported symptom in patients with multiple sclerosis (MS). It is a worrisome, frequent, and debilitating manifestation that could occur at any time during the course of MS and in all its subtypes. It could engender professional, familial, and socioeconomic consequences and could severely compromise the patients' quality of life. Clinically, the symptom exhibits motor, cognitive, and psychosocial facets. It is also important to differentiate between perceived or subjective self-reported fatigue and fatigability which is an objective measure of decrement in the performance of cognitive or motor tasks. ... read more

  • Causal evidence of the roles of the prefrontal and occipital cortices in modulating the impact of color on moral judgement
    Neuropsychologia. 2022 May 11:108267. doi: 10.1016/j.neuropsychologia.2022.108267. Online ahead of print.ABSTRACTMoral judgment is known to be affected by factors such as color. Previous research has shown that the colors black and white are particularly important, however, the neural mechanisms underlying this effect remain unclear. This study aimed to investigate the causal relationship between specific brain regions (left dorsolateral prefrontal cortex, left DLPFC and occipital cortex, OC) and their impact of black and white moral judgement by using transcranial direct current stimulation (tDCS). The results of Experiment 1 (N = 54) and Experiment 2 (N = 66) showed that anodal tDCS over ... read more

  • Transcranial direct current stimulation to modulate brain reactivity to food cues in overweight and obese adults: study protocol for a randomized controlled trial with fMRI (NeuroStim-Obesity)
    Trials. 2022 Apr 12;23(1):297. doi: 10.1186/s13063-022-06234-8.ABSTRACTBACKGROUND: With increasing obese populations worldwide, developing interventions to modulate food-related brain processes and functions is particularly important. Evidence suggests that transcranial direct current stimulation (tDCS) over the dorsolateral prefrontal cortex (DLPFC) may modulate the reward-control balance towards facilitation of cognitive control and possible suppression of reward-related mechanisms that drive food cue-induced craving. This protocol describes a clinical trial that investigates the neurocognitive mechanisms of action for tDCS to modulate food cue-reactivity and cravings in people with obesity.METHOD: The NeuroStim-Obesity trial is a prospective, randomized, sham-controlled, double-blind single-session tDCS trial targeting food craving in those ... read more

  • Effects of Prefrontal Transcranial Direct Current Stimulation on Retention of Performance Gains on an Obstacle Negotiation Task in Older Adults
    Neuromodulation. 2022 Apr 8:S1094-7159(22)00561-X. doi: 10.1016/j.neurom.2022.02.231. Online ahead of print.ABSTRACTOBJECTIVES: Complex walking in older adults can be improved with task practice and might be further enhanced by pairing transcranial direct current stimulation (tDCS) to the dorsolateral prefrontal cortex. We tested the hypothesis that a single session of practice of a complex obstacle negotiation task paired with active tDCS in older adults would produce greater within-session improvements in walking performance and retention of gains, compared to sham tDCS and no tDCS conditions.MATERIALS AND METHODS: A total of 50 older adults (mean age = 74.46 years ± 6.49) with self-reported walking difficulty ... read more

  • Distinguishing the Roles of the Dorsomedial Prefrontal Cortex and Right Temporoparietal Junction in Altruism in Situations of Inequality: A Transcranial Direct Current Stimulation Study
    Front Hum Neurosci. 2022 Mar 23;16:821360. doi: 10.3389/fnhum.2022.821360. eCollection 2022.ABSTRACTThe right temporoparietal junction (rTPJ) and dorsomedial prefrontal cortex (dmPFC), which are involved in social cognition, have been proposed to play key roles in guiding human altruistic behavior. However, no study has provided empirical evidence that the rTPJ and dmPFC play distinct roles in altruism under situations of inequality. A total of 107 healthy young adults were randomly assigned to receive anodal or sham transcranial direct current stimulation (tDCS) to either the dmPFC or rTPJ, and they participated in a modified dictator game. The stimulation of the dmPFC increased the level ... read more

  • Therapeutic Effect of Multi-Channel Transcranial Direct Current Stimulation (M-tDCS) on Recovery of Cognitive Domains, Motor Functions of Paretic Hand and Gait in Subacute Stroke Survivors-A Randomized Controlled Trial Protocol
    Neurosci Insights. 2022 Mar 30;17:26331055221087741. doi: 10.1177/26331055221087741. eCollection 2022.ABSTRACTBACKGROUND: There has been rapid drift of rehabilitation professionals toward the clinical use of technology aided electrical interventions. Brain is a cortical hub of functionally related neural connections. Motor learning entails strong interaction with the cognitive domains. So better outcomes may be expected by optimally targeting functionally correlated areas simultaneously through tDCS.AIM: To determine the therapeutic effect of Multi Channel tDCS in combination with Functional electrical stimulation, SaeboFlex and conventional rehabilitation on recovery of Cognitive Domains, Motor Functions of Paretic Hand, and Gait in individuals with subacute Stroke.METHODS: This is prospective, randomized, ... read more
