The first level of analysis will be the generation of fMRI maps of brain activity using FMRIB Software Library (FSL), a statistical software package specifically designed for fMRI applications, which uses the general linear model to compute contrast parameter estimates of explanatory variables (in our case, the explanatory variable is face task vs. sensorimotor task) for each pixel in the brain images. The result is an estimate of the response magnitude in a given pixel that surpasses a specified statistical threshold (typically, p = 0.01).
