1. A method for selecting a stimulation site in a language-disorder patient, comprising: administering a neuroexcitatory drug to a patient; directing a patient to perform a language-based task, including directing the patient to repeat a noun; directing information to be collected while the patient performs the language-based task with the neuroexcitatory drug active in the patient's body, the information corresponding to a level of neural activity in the patient's brain while the patient performs the language-based task; and based at least in part on the information, selecting a stimulation site within the patient's skull, proximate the dura mater, and outside a cortical surface of the patient's brain for receiving an electrode coupleable to an electrical current.
