A new variation of MRI – called DIANA or direct imaging of neuronal activity – hopes to track the propagation of brain signals on millisecond timescales, according to a study published by Science magazine on October 13, 2022. The technique uses existing MRI equipment, but with a burst of quick images over a very small area. Physicians and scientists can see high-resolution changes on a millisecond basis by viewing the whole sequence of images. The technique is still being tested, since it may be susceptible to so-called motion artifacts -- disruptions caused by the animal or patient moving between takes. The technique also requires powerful MRI equipment.

Neuro-Innovators LLC, a Pittsburgh-based clinical-stage company developing drugs to promote neuroplasticity and treat brain injury and diseases, has welcomed Dr. George F. Wittenberg, MD, Ph.D., to its Scientific Advisory Board. 

Dr. Wittenberg’s research focuses on rehabilitation following stroke and brain injury, and he has extensive experience in upper-body rehabilitation using transcranial magnetic stimulation (TMS), robotics for repetitive physical exercises, virtual reality training, and other methods
