FIGURE 15.7 Functional neuroimaging demonstrates localizationof function in the human cerebral cortex Functional magneticresonance imaging (fMRI) shows increased activity of particular brainareas. This fMRI sectional image of a brain (seen from above; leftis anterior) shows increased neural activity during a visual stimulus.The neural activity (measured as increased flow of oxygenated bloodand shown in red) increases in the lateral geniculate nucleus of thethalamus (middle) and the primary visual cortex (posterior). (See Figure14.32 for a diagrammatic view of this pathway and Box 15.2 for a discussionof fMRI as an imaging method.) (From Chen et al. 1999.)
