Experiment staging. Subjects were transported to McLean Hospital on a Th or F for the first imaging session, during which subjects were anesthetized, underwent a baseline ³¹P MRS scan, were administered TLTs, and then underwent three additional post-TLT ³¹P MRS scans. Then, subjects were recovered from anesthesia and transported to their housing location at Toxikon. Over the next 2 weeks, awake subjects were administered identical TLTs on M, W, and F, and then were transported to McLean Hospital to undergo a second scan session identical to the first session on M or Tu. F, Friday; M, Monday; Th, Thursday; TLT, transcranial laser treatment; Tu, Tuesday; W, Wednesday.
