Phineas Gage as a reference for incorporating data from multiple modern clinical cases, enumerating damaging cognitive effects when feelings and reasoning become anatomically decoupled. The book provides an analysis of diverse clinical data contrasting a wide range of emotional changes following frontal lobe damage as well as lower (medulla) and anterior areas of the brain such as the
anterior cingulate. Among his experimental evidence and testable hypotheses, Damásio presents the "
