Numerous studies have emerged recently that demonstrate the possibility of modulating, and in some cases enhancing, cognitive processes by exciting brain regions involved in working memory and attention using transcranial electrical brain stimulation. Some researchers now believe the cerebellum supports cognition, possibly via a remote neuromodulatory effect on the prefrontal cortex. This paper...

Introduction: It is believed that injury potential has a regulatory role in wound healing process and the application of exogenous electrical stimulation may serve to mimic the natural endogenous bioelectric current so that can improve the wound healing. Up to now, this hypothesis has not been researched in surgically acute wounds. Materials and Methods: Thirty nine male guinea pigs were random...

PURPOSE Weak direct currents induce lasting alterations of cortical excitability in animals and humans, which are controlled by polarity, duration of stimulation, and current strength applied. To evaluate its anticonvulsant potential, transcranial direct current stimulation (tDCS) was tested in a modified cortical ramp-stimulation model of focal epilepsy. METHODS The threshold for localized s...

Abstract The subjective presence experience in virtual reality (VR) is associated with distinct brain activation patterns. Particularly, the dorsolateral prefrontal cortex (DLPFC) seems to play a central role. We investigated effects of electric stimulation (transcranial direct current, tDCS) on as well activity and connectivity. Thirty-eight participants received either anodal ( N = 18) or cat...

The present study investigated emotional memory following bilateral transcranial electrical stimulation (direct current of 1 mA, for 20 minutes) over fronto-temporal cortical areas of healthy participants during the encoding of images that differed in affective arousal and valence. The main result was a significant interaction between the side of anodal stimulation and image emotional valence. ...

Motor cortex (MCX) motor representation reorganization occurs after injury, learning, and different long-term stimulation paradigms. The neuromodulatory approach of transspinal direct current stimulation (tsDCS) has been used to promote evoked cortical motor responses. In the present study, we used cathodal tsDCS (c-tsDCS) of the rat cervical cord to determine if spinal cord activation can modi...

Quantitative extracellular electrical stimulation data were obtained from single fibers in the dorsal columns of anesthetized and paralyzed cats. Single-fiber responses were recorded with glass microelectrodes. The threshold current was found for fibers stimulated with a 100-p diameter monopolar electrode at the surface of the dorsal columns 0.5-2.0 cm from the recording electrode. Shock artifa...

Background: Pain is of stressful and unpleasant procedures after daily dressing of burn wound, so that if the burn pain is not alleviated properly, it can cause harmful effects other than discomfort. There is evidence that cathodal stimulation of somatosensory cortex can be effective in relieving acute pain. Aim: The main purpose of this study was to determine the effect of Direct Transcranial ...
