The deficit-lesion method for studying brain function before functional neuroimaging techniques became available, the only ways to study brain function were animal research. Specifically, investigators compared the rate of lesion loss due to atrophy to the appearance or enlargement of lesions both at the start of the study and at five or 10 years of follow-up. While lesion studies in humans have provided key insights into brain organization and function, lesions studies in animals offer many advantages first, animals used in research are reared in controlled environmental conditions that limit variability between subjects.
