Repetitive Transcranial Magnetic Stimulation (rTMS): Summary and Introduction. Transcranial Direct-Current Stimulation. Effects of Transcranial Direct Current Stimulation on Episodic Memory Related to Emotional Visual Stimuli. 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. Specifically, right anodal/left cathodal stimulation selectively facilitated the recall of pleasant images with respect to both unpleasant and neutral images whereas left anodal/right cathodal stimulation selectively facilitated the recall of unpleasant images with respect to both pleasant and neutral images.

It sounds like quackery, but it's not. “You could use this to boost your brainpower at the flick of a switch” Busteed isn't here to test commercial devices, however. Busteed is one of 20 patients in a phase II clinical trial led by Eric Wassermann, head of the brain stimulation unit at the US National Institute of Neurological Disorders and Stroke (NINDS) in Bethesda, Maryland.
If the trial proves successful, Wassermann would like to develop a brain stimulation device that patients can take home and use whenever they want. Zapping the brain with electricity to cure various maladies has slipped in and out of vogue over the past two millennia (see "Zaps from the past"). Administering tDCS is relatively easy. The Göttingen team isn't the only one with success stories.
Transcranial direct current stimulation. Transcranial direct current stimulation (tDCS) is a form of neurostimulation which uses constant, low current delivered to the brain area of interest via electrodes on the scalp. It was originally developed to help patients with brain injuries such as strokes. Tests on healthy adults demonstrated that tDCS can increase cognitive performance on a variety of tasks, depending on the area of the brain being stimulated.[1] It has been utilized to enhance language and mathematical ability, attention span, problem solving, memory, and coordination.[1] Effects on brain[edit] Neuroplasticity refers to the ability of the brain to change throughout life based on experiences.
Safety[edit] When applied following established safety protocols, transcranial direct current stimulation is widely regarded as a safe method of brain stimulation, causing no apparent short-term harm. Safety protocol[edit] Studies have been completed to determine the current density at which overt brain damage occurs in rats. Google Image Result for. Broadcast Yourself.
