Purpose of review Brain electrical stimulation has been proposed as a strategy to improve chronically impaired cognitive function. This brief review places a small number of recent studies into a broader historical context and identifies important challenges for further development of this area of research. Recent findings Behavioral improvements following severe brain injury with central thalamic deep brain stimulation were observed in experimental studies conducted in rodents and a report on

Summary This area of research offers the promise of new avenues to engage patients with nonprogressive brain injuries who, at present, have rather limited therapeutic options. These efforts, however, will require careful attention to issues of research and clinical ethics and study design. . This is a detailed, up-to-date, and clinically oriented review of applications of DBS in neuropsychiatric disorders. 2 Liu Y, Postupna N, Falkenberg J, Anderson ME. High frequency deep brain stimulation: What are the therapeutic mechanisms? Neurosci Biobehav Rev 2006; 20 Dec [Epub ahead of print]. This is a recent review of experimental studies conducted by an investigative physiology group that emphasizes network modulation as a unifying framework for interpretation of in-vitro and in-vivo experimental findings.
