Reviva Brain Developed within the early, positron emission tomography imaging imaging includes injecting small portions of a radioactive substance into the body. This ‘radiotracer’ binds to unique molecules within a particular body organ or tissue; the gamma rays it emits can be detected thru the scanner, which then produces three-dimensional snap shots displaying the ranges and distribution of the radiation within the form.The method contributed mainly to our know-how of the healthy and diseased thoughts due to the creation of tracers that bind to oxygen, which gave researchers a brand new manner of investigating brain metabolism. https://medium.com/@naliejuriya/physical-exercise-to-increase-brain-8a7e919c9671
