The disclosed embodiments relate to a system and method for detecting a response of a patient to an external stimulus. An exemplary method comprises the acts of generating at least one time series of at least one physiologic parameter, detecting the external stimulus, detecting at least one response associated with the stimulus, the response comprising at least one of a pattern and a value, and outputting an indication of the response.
