neural circuits. Indeed, it could even be the case that the equal populace of neurons can guide specialcognitive capabilities. Thus, pastime of a vicinity in or extra obligations, or impairment on a couple of dutiesbecause of a unmarried, small lesion, is probably explained both by a not unusual underlying feature orthrough more than one capabilities (Duncan & Owen, 2000; Farah, 1994; Shallice, 1988; Rumelhart &McClelland, 1986). Finally, both lesion technique and purposeful imaging percentage a reliance on ceterisparibus assumptions: that a unmarried variable is being manipulated and all other things are equal. Ceterisparibus assumptions create troubles which can be method-precise, however the underlying philosophicalissue is one that every one strategies percentage. For example, in lesion studies, a loss of reorganization isnormally assumed: All other neural regions in a lesioned mind are assumed to be appearing the same tasksthey achieved previous to lesion acquisition, and now not acquiring the capabilities of the lesioned region.(This assumption almost simply does not keep in chronic-stage lesion sufferers; Farah, 2004.) In functionalimaging research, it is assumed that two tasks that differ theoretically in a unmarried cognitive manner do nolonger differentially recruit neural regions for theoretically shared project components (Posner, Petersen, Fox,& Raichle, 1988). (This assumption is also unlikely to keep; Friston et al., 1996.) In addition to those sharedinferential issues, there is an vital distinction in the types of inferences that can be drawn from functionalimaging and lesion methods. In comparison to lesion research, useful imaging studies are necessarily
