"Nevertheless, there is clearly a growing excitement around treating neurological diseases using neuromodulation, rather than pharma-ceuticals. “There’s pretty good evidence that by changing neural-circuit activity we can get improvements in Parkinson’s, chronic pain, obsessive–compulsive disorder and depression,” says Insel. This is important, he says, because so far, pharmaceutical treatments for neurological disease have suffered from a lack of specificity. Koroshetz adds that funding institutes are eager for treatments that are innovative, non-invasive and quickly translatable to people."

(Sharon Richardson comments: I have been using neurofeedback therapy for over a year. Recent post SPECT imaging shows a more balanced blood flow -- increases where neurons were idling; decreases where neurons were overactive. This is an exciting new area of research in neurological disease patterns)

Neuroscientists are getting excited about non-invasive procedures to tune the brain’s natural oscillations.
