Résumé
The description by Jules Joseph Dejerine and Augusta Dejerine-Klumpke (1895) of the fiber connections uniting diverse brain areas have become, in modern times, association fibers. These were proposed as a biological basis for corroborating or refuting medical hypotheses derived from the clinical consequences of brain injury – often interpreted considering such theoretical perspectives as localizationism, holism, or associationism. Given the 3D nature of these association networks, however, anatomical dissections are somewhat arbitrary with respect to what one is trying to find. More recently, new structural and functional techniques have been developed with the hope of objectively untangling the useful reality suggested by these association networks. These past years, there has been much interest in mapping the connectome – the complete map of neural connections in a nervous system of a given species – to understand how brain structure gives rise to brain function, and ultimately, how it generates behaviour.
