The Glasgow Coma Scale (ECG) is a globally recognized scale for the classification of patients with traumatic brain injury according to their neurological compromise. This scale assesses eye opening, verbal response, and motor response. Functional neuroanatomy represents a sequential commitment to decrease the score of each of these items. The objective of this review is to describe the anatomy of the ascending activating reticular system (SARS), the functional anatomy of language, the anatomy of the brain stem and the motor pathways that represent each item evaluated by the ECG.
