ROSALES F, Rosario et al. OBTENCION DE MAPAS CORTICALES DE AREAS MOTORA Y VISUAL, CON RESONANCIA MAGNETICA CEREBRAL FUNCIONAL. Rev. chil. radiol. [online]. 2006, vol.12, n.4, pp.164-169. ISSN 0717-9308. http://dx.doi.org/10.4067/S0717-93082006000400006.
Functional magnetic resonance imaging (fMRI) is a non-invasive imaging tool that measure regional cerebral blood flow related changes. Functional MR mapping of the sensory-motor cortex and visual cortex was performed in 24 healthy volunteers. The visual areas in individual subjects were mapped through passively viewing a video stimulus. The activation motor test consisted of a simple hand movement. In both cases, a functional cortical map was obtained. Presurgical mapping of the sensory-motor cortex and visual cortex is a potentially usefull clinical application of fMRI
