Transcranial direct current stimulation (tDCS) is a neuromodulatory technique that delivers low intensity, direct current to cortical areas facilitating or inhibiting spontaneous neuronal activity. This paper investigates how normal variations in anatomy may affect the current flow through the brain. This was done by applying electromagnetic computational methods to human models of different ag...

BACKGROUND Traditional treatment for motor impairment after stroke includes medication and physical rehabilitation. The transcranial direct current stimulation associated with a standard physical therapy program may be an effective therapeutic alternative for these patients. METHODS This study is a sham-controlled, double-blind, randomized clinical trial aiming to evaluate the efficacy of tra...

Noninvasive cortical stimulation techniques, such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), have proved to be powerful tools for establishing causal relationships between brain regions and their functions. In the present study, we demonstrate that a new technique called transcranial alternating current stimulation (tACS) can interact with ong...

transcranial magnetic stimulation (tms) has been applied to a growing number of psychiatric disorders as a neurophysiological probe, a primary brain-mapping tool and a candidate treatment. although most investigations have focused on the treatment of major depression, increasing attention has been paid to anxiety disorders. the aim of this study is to long time (for 30 days) effect of repetitiv...
