IMPLEMENTACIóN Y VALIDACIóN DE PROTOCOLO DE ESTIMULACIóN POR COMPRENSIóN DE LENGUAJE ORAL EN RESONANCIA MAGNéTICA FUNCIONAL: RESULTADOS PRELIMINARES

this study aimed at implementing a stimulation protocol using functional magnetic resonance imaging (fmri), in a hospital in valparaiso (v region), chile, to detect cortical areas activated in oral language comprehension. seven healthy volunteers participated in this study. average t-score and signal variation were 6.3±0.3 and 0.5±0.1%, respectively. in spite of these low values, activations were obtained in wernicke area, middle temporal gyrus, and heschl s gyrus. the extension of activated areas was small, 5.06±2.99 cm3, probably due to amplifer low signal-to-noise ratio (snr), in addition to the cognitive complexity of the task, and to the ambient acoustic noise. successful implementation of fmri protocols of language comprehension is possible in a clinical context in chile without any additional resources.
