Imaging a science of mind.
I believe that the study of neuroimaging has supported localization of mental operations within the human brain. Most studies have shown a small number of widely distributed brain areas that must be orchestrated to carry out a cognitive task. Although, as in all sciences, there are disagreements, the convergence of results in areas of attention and language in particular seem impressive. Moreover, the anatomical data has helped us to specify the computations that are used by the brain to carry out cognitive tasks. Building upon localization of cognitive operations, imaging methods are being applied to studies of the circuitry, plasticity and individual development of neural networks. Working together with cellular and genetic methods, there is movement towards a more unified view of the role of the human brain in supporting the mind.
