The U.S. Brain Research Through Advancing Innovative Neurotechnologies (BRAIN) Initiative is a collaboration among the National Institutes of Health, Defense Advanced Research Projects Agency, National Science Foundation, Food and Drug Administration, Intelligence Advanced Research Projects Activity, and others. Since its inception in 2013, its goal has been to develop and use new technologies to examine how each neuron and neural circuit come together to “record, process, utilize, store, and retrieve vast quantities of information, all at the speed of thought.”
