Brain Stimulation And Ethics
Transcranial direct current stimulation (or TDCS), is a type of non-invasive brain stimulation in which weak electrical currents are applied to the head via electrodes for a short time (about 20 minutes). The effects of this brain stimulation can last up to 12 months and can elicit changes in neurotransmitter concentrations. Most research has focused on using this type of stimulation as a means to improve the cognitive capacities of people with certain psychological or cognitive disabilities. But recent research has shown that TDCS may also improve the cognitive capacities of those without such disabilities. Studies have shown that several aspects of cognition may be improved, such as motor skills, vision, decision making, mathematical cognition, language and memory. read more
