The anatomical understanding of cortical and subcortical distribution of language is beyond the already known Broca's and Wernicke's areas (44 and 22 of Brodmann) and the connection between themselves through de arcuate fascicule. The cortical and subcortical network extension is consisten with the idea that language comprehension is a complex process in which, like in another human behaivours, exists a coordinated activity between several brain regions, each one performing subprocesses integrated to develop final comprehension. Finally, it results essential to know the anatomy of these pathways and their connections in order to understand the functionality in case of pathology and the ulterior recovery. The aim of this work is to show and describe using DTI-MR and corticographies, the normal anatomy of the subcortical bundles which compose the language pathways. Define anatomical landmarks to identify cortical areas and language pathways in Magnetic Resonance Imaging. By tractography, white matter bundles implied in the processing of language were searched according to previous anatomical descriptions: superior longitudinal fascicle, arcuate fascicle, inferior longitudinal fascicle, inferior frontooccipital fascicle and extreme capsule. Then, using MRI the previously mentioned tracts and the areas involved in language were localized. Finally, 3 patients were studied from intraoperatory electrostimulation in which cortical areas of language were mapped. The forming areas and pathways of the language were successfully localized.
