Identifying cardiorespiratory neurocircuitry involved in central command during exercise in humans

For almost one hundred years the brain's ,central command, system , whose charge includes controlling the body's cardiorespiratory response to exercise , has been pursued. Animal experiments and functional imaging studies have provided clues to the location of this system, but the underlying electrophysiological activity has never been measured.
