 Functional dissociability is associated with neural localizability in a strong sense. A system is strongly localized just in case it is (a) implemented in neural circuitry that is both relatively circumscribed in extent (though not necessarily in contiguous areas) and (b) dedicated to the realization of that system alone. Localization in this sense goes beyond mere implementation in local neural circuitry, since a given bit of circuitry could subserve more than one cognitive function (Anderson, 2010). Proposed candidates for strong localization include systems for color vision (V4), motion detection (MT), face recognition (fusiform gyrus), and spatial scene recognition (parahippocampal gyrus).
