Claim 0:
1. A method of identifying a non-penetrating brain injury in a subject that has experienced a brain injury, the method comprising:
(a) fitting the subject with electrodes to measure voltage potentials generated from the subject's brain;
(b) administering to the subject an acoustic stimulus comprising a complex sound;
(c) recording voltage potentials from the subject's brain for at least the duration of the acoustic stimulus;
(d) analyzing the voltage potentials to determine at least one component of the brain response to the acoustic stimulus; and
(e) identifying the subject as having a non-penetrating brain injury if a 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.
