Claim 21:
22. A system for identifying a brain injury, the system comprising a computing device comprising at least one processor configured to:
receive an indication of a brain injury of a subject;
in response to the indication, immediately perform an evaluation of the subject's brain response to an acoustic stimulus by:
generating an acoustic stimulus comprising a complex sound;
obtaining voltage potential data from a brain response corresponding to an auditory pathway of a subject, wherein the voltage potential data is obtained during presentation of the acoustic stimulus to the subject;
analyzing the voltage potential data to determine at least one component of the brain response; and
generating and storing, in a memory in operable communication with the at least one processor, an indication of a non-penetrating brain injury when a first value for at least one component of the brain response is anomalous;

wherein the at least one component of the brain response is fundamental frequency (F0), neural timing of a sustained response peak, response amplitude over a time window that comprises some or all of the complex sound, or stimulus-response correlation over a time window that encompasses some or all of the complex sound.
