[EN]Background. It is a fact that students, professors and physicians
show difficulties in learning and teaching the way to identify the
speech areas and their connections, specially neurosurgeons to
locate and assess the indication or contraindication of surgery
due to the need of preserving the function. Purpose. The aim of
this paper is to demonstrate the major role and development of
the new functional MR (fMR) techniques on the language areas,
because they are not only used to assess the brain morphology
but also the language function. Diffusion tensor tractography
assesses the connections of the language-related areas by the
white matter tracts. Method. We present a large amount of
images of brain-CT, fMR and diffusion tensor tractography of
the eloquent areas. Results. Brain speech areas and their
connections by the white matter tracts are visually illustrated
and described. Images prove to be very useful to understand the
complexity of the language system and to locate speech areas
avoiding the inter and intra individual variability. Conclusions.
The application of this technology makes possible the visual
learning of the complexity of the language system as well as the
assessment and accurate delimitation of the brain damages and
their relationship with the motor and eloquent areas of the brain.
