Electrical Brain Stimulation Could Support Stroke Recovery, Says Study

Oxford, UK (Scicasts) — Applying an electric current to the brain can help recovery from stroke, Oxford University researchers have found. Their research is published in the journal Science Translational Medicine. A team from Oxford’s Nuffield Department of Clinical Neurosciences, led by Professor Heidi Johansen-Berg and Dr. Charlotte Stagg, studied the use of transcranial direct current stimulation (tDCS) to support rehabilitation training. The technique involves placing electrodes on the scalp to pass a constant low current through a particular area of the brain. In this case, the team used a variant called ipsilesional anodal tDCS, where a positive (anodal) current is applied on the side of the brain where damage has occurred. Anodal stimulation has previously been shown to increase the learning of motor skills in healthy people. The hope…
