Brain Stimul. 2018 Apr 05;: Authors: Leffa DT, Bellaver B, Salvi AA, de Oliveira C, Caumo W, Grevet EH, Fregni F, Quincozes-Santos A, Rohde LA, Torres ILS Abstract BACKGROUND: Transcranial direct current stimulation (tDCS) is a technique that modulates neuronal activity and has been proposed as a potential therapeutic tool for attention-deficit/hyperactivity disorder (ADHD) symptoms. Although pilot studies have shown evidence of efficacy, its mechanism of action remains unclear. OBJECTIVE/HYPOTHESIS: We evaluated the effects of tDCS on behavioral ... read more

  • Cognitive Neuroscience of Attention Deficit Hyperactivity Disorder (ADHD) and Its Clinical Translation.
    Related ArticlesCognitive Neuroscience of Attention Deficit Hyperactivity Disorder (ADHD) and Its Clinical Translation. Front Hum Neurosci. 2018;12:100 Authors: Rubia K Abstract This review focuses on the cognitive neuroscience of Attention Deficit Hyperactivity Disorder (ADHD) based on functional magnetic resonance imaging (fMRI) studies and on recent clinically relevant applications such as fMRI-based diagnostic classification or neuromodulation therapies targeting fMRI deficits with neurofeedback (NF) or brain stimulation. Meta-analyses of fMRI studies of executive functions (EFs) show that ADHD patients have cognitive-domain dissociated complex multisystem impairments in several right and left hemispheric dorsal, ventral and medial fronto-cingulo-striato-thalamic and fronto-parieto-cerebellar networks that mediate cognitive ... read more

  • Can 8 months of daily tDCS application slow the cognitive decline in Alzheimer’s disease? A case study.

Neurocase. 2017 Apr;23(2):146-148 Authors: Bystad M, Rasmussen ID, Grønli O, Aslaksen PM Abstract This case study presents a patient with early-onset Alzheimer`s disease, who applied transcranial direct current stimulation (tDCS) daily for 8 consecutive months. This was a much higher frequency than previous tDCS studies. Neuropsychological assessments were conducted before the first tDCS session, after 5 months and after 8 months. After 8 months, the patient's immediate recall improved with 39%, whereas delayed recall improved 23%. Overall, the results revealed that patient's cognitive functions were ... read more

  • On the effectiveness of event-related beta tACS on episodic memory formation and motor cortex excitability.
    Related ArticlesOn the effectiveness of event-related beta tACS on episodic memory formation and motor cortex excitability. Brain Stimul. 2017 Sep - Oct;10(5):910-918 Authors: Braun V, Sokoliuk R, Hanslmayr S Abstract BACKGROUND: Transcranial alternating current stimulation (tACS) is widely used to entrain or modulate brain oscillations in order to investigate causal relationships between oscillations and cognition. OBJECTIVE: In a series of experiments we here addressed the question of whether event-related, transient tACS in the beta frequency range can be used to entrain beta oscillations in two different domains: episodic memory formation and motor cortex excitability. METHODS: In experiments 1 and ... read more

Trends Cogn Sci. 2018 Mar 27;: Authors: Widge AS Abstract Transcranial electrical stimulation (TES) is a proposed tool for noninvasively modulating human brain circuits, but its ability to affect cortical physiology remains unclear. A recent study merged TES with live animal and human cadaveric recordings to verify intracranial electrical effects, then used these findings to develop a novel neuromodulation protocol.PMID: 29602532 [PubMed - as supplied by publisher] ... read more

  • Self-generation and positivity effects following transcranial random noise stimulation in medial prefrontal cortex: A reality monitoring task in older adults.
    Related ArticlesSelf-generation and positivity effects following transcranial random noise stimulation in medial prefrontal cortex: A reality monitoring task in older adults. Cortex. 2017 06;91:186-196 Authors: Mammarella N, Di Domenico A, Palumbo R, Fairfield B Abstract Activation of medial Prefrontal Cortex (mPFC) has been typically found during reality monitoring tasks (i.e., distinguishing between internal self-generated vs external information). No study, however, has yet investigated whether transcranial Random Noise Stimulation (tRNS) over the mPFC leads to a reduction in reality-monitoring misattributions in aging. In particular, stimulating mPFC should increase the number of cognitive operations engaged while encoding and this distinctive information may ... read more

  • Targeting the Cerebellum by Noninvasive Neurostimulation: a Review.
    Related ArticlesTargeting the Cerebellum by Noninvasive Neurostimulation: a Review. Cerebellum. 2017 Jun;16(3):695-741 Authors: van Dun K, Bodranghien F, Manto M, Mariën P Abstract Transcranial magnetic and electric stimulation of the brain are novel and highly promising techniques currently employed in both research and clinical practice. Improving or rehabilitating brain functions by modulating excitability with these noninvasive tools is an exciting new area in neuroscience. Since the cerebellum is closely connected with the cerebral regions subserving motor, associative, and affective functions, the cerebello-thalamo-cortical pathways are an interesting target for these new techniques. Targeting the cerebellum represents a novel way to ... read more
