Behavior-brain-gene Approach

Method of deducing the relationships of disorders with a complex etiology, especially behavioral disorders, by examining a system with a top-down model, i.e. from an abnormal condition or behavior, to its set of physiological conditions, to its genetic component and perhaps even specific gene(s). Examples are schizophrenia, mood disorder, and autistic disorder.

Cf. genebrain-behavior approach.
