Aspectos Neuropsicológicos de la Resonancia Magnética Funcional.

Cognitive neuropsychology and functional magnetic resonance (RMf) have marked a particularly fertile period in the development of neurosciences. Their clinical value, although incipient, is unquestionable. Integration of these two disciplines allows the registration  of cerebral images related to the neuronal activation of specific areas, providing structural and functional information of the human brain  under normal and pathological conditions. The RMf has important clinical and research applications. For example, pointing the brain  areas needed to be avoided during surgery, or observing the neurofunctional changes that take place with a  pharmacological treatment or neuropsychological rehabilitation. It also permits increasing the knowledge of  neurofunctional bases of different cerebral pathologies. It  is of special interest and importance the selection and implementation of the activation paradigm on functions to be studied, condition that  is required for the correct interpretation of the results. The procedure for RMf allows the study of a specific component in the  cognitive process in response to a specific task. It doesn’t identify the function as a unique feature, but it  identifies neurofunctional patterns. In this  article, the basic theoretical-methodological neuropsychological aspects are described for the implementation of studies by RMf.
