History of neuropsychology shows, during last and the beginning of the present centuries, a marked trend to localization and association (one center for each function, followed later by a period where globalistic trends predominate, according to which a localized lesion is important mostly because of the modification it produces in the functions of brain as a whole. During the last 30 years, the development of anatomoclinical methods and experimental neuropsychology have again given impulse to a neoassociational trend. By their importance, recent advances in the following topics are underlined: (1) The study of behaviour, particularly regarding the role of neurotransmitters.
