Orasi Index >> MEG/EEG
An Objective Measure of Brain Activity

Since the first MEG scan in 1968, MEG has rapidly advanced with scans now able to localize sources with unmatched temporal and spatial resolution. MEG is most commonly used for the study of pathological activity associated with epilepsy and for pre-surgical mapping of brain function. Orasi’s technology is based on more than five years of research and development at the University of Minnesota and the Minnesota VA Medical Center and is specific to the application of MEG technology for the study of neuroactive drug action and CNS disorders.

  • MEG measures the brain's magnetic and electrical signature
  • No radiation, no injections and no noise - safe and patient friendly
  • Quick: 5-10 minutes (resting state analysis)
  • Scan cost is comparable to MRI
  • 120+ installed MEG's - located at major research institutions

MEG--provides the most accurate data -in milliseconds.
Neuronal electrical activity generates magnetic fields that penetrate the skin and scalp undisturbed. MEG technology measures those tiny magnetic signals in real-time to accurately determine the locations and relationships between neurons. The ability to measure rapid events offers a substantial advantage over other neuroimaging technologies such as fMRI, PET, and SPECT, which are unable to follow synaptic events as they occur.
