Previous results point towards a lateralization of dorsolateral prefrontal cortex (DLPFC) function in risky decision making. While the right hemisphere seems involved in inhibitory cognitive control of affective impulses, the left DLPFC is crucial in the deliberative processing of information relevant for the decision. However, a lack of empirical evidence precludes definitive conclusions. The ...

Daily management of neurodegenerative diseases is one of the most striking scenarios where an integrated health care system is essential for the continuous assistance to the patient and requires qualification of the caregivers and their training. In particular, patients affected by depression or chronic pain, as well as rehabilitating after stroke, can be treated at home with non-invasive elect...

The limits of human visual short-term memory (VSTM) have been well documented, and recent neuroscientific studies suggest that VSTM performance is associated with activity in the posterior parietal cortex. Here we show that artificially elevating parietal activity via positively charged electric current through the skull can rapidly and effortlessly improve people's VSTM performance. This artif...

A number of studies have linked the blood oxygenation level dependent (BOLD) signal to electroencephalographic (EEG) signals in traditional frequency bands (δ, θ, α, β, and γ), but the relationship between BOLD and its direct frequency correlates in the infraslow band (<1 Hz) has been little studied. Previously, work in rodents showed that infraslow local field potentials play a role in functio...

objective: recent studies on treating obsessive compulsive disorder (ocd) have investigated noninvasive brain stimulation techniques such as transcranial direct current stimulation (tdcs) to improve patients’ impaired emotion and cognition. however, such experiments have yielded mixed results, especially with respect to cognition. this study aimed to investigate whether anodal and cathodal tdcs...

The clinical use of direct current shock in the management of cardiac arrhythmias (Lown, Amarasingham, and Neuman, 1962) has been amply confirmed by many other workers (O'Brien, Resnekov, and McDonald, 1964; Oram et al., 1964; Morris et al., 1964b). The length of time that sinus rhythm persists after the electrical conversion of chronic arrhythmias is often disappointingly short, even when quin...

It is well known that living cells have bioelectrical phenomena which could be affected by electric field alteratious. Exposure to an electric field causes considerable changes in metabolic, immunologic and physiologic aspects of biological systems. The possible effect of electrical stimuli on various tissues, in vitro and in vivo, have been anticipated. In this regard, electrotherapy with the ...

As important non-invasive techniques in brain stimulation, transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) have been studied and compared in this paper by employing impedance method and a 3D human head model. The quantitative analysis of distributions of current density and electric field by tDCS and TMS have been presented. Results are compared and po...

Adaptation to a novel visuomotor transformation has revealed important principles regarding learning and memory. Computational and behavioral studies have suggested that acquisition and retention of a new visuomotor transformation are distinct processes. However, this dissociation has never been clearly shown. Here, participants made fast reaching movements while unexpectedly a 30-degree visuom...

Transcranial cerebellar direct current stimulation (tDCS) and transcutaneous spinal DCS (tSDCS) are two innovative neuromodulatory techniques based on applying direct current (DC) non-invasively through the skin. Previous experimental works showed that weak DC delivered transcutaneously in humans over the cerebellum and over the spinal cord for minutes could elicit prolonged changes in neurophy...
