neural circuits. Indeed, it is able to even be the case that the equal population of neurons can helpextraordinary cognitive functions. Thus, pastime of a region in or greater duties, or impairment on more thanone duties because of a single, small lesion, might be explained either by means of a commonplaceunderlying feature or by more than one functions (Duncan & Owen, 2000; Farah, 1994; Shallice, 1988;Rumelhart & McClelland, 1986). Finally, both lesion technique and practical imaging percentage a relianceon ceteris paribus assumptions: that a single variable is being manipulated and all other things are same.Ceteris paribus assumptions create problems that are approach-unique, however the underlying philosophicaldifficulty is one that every one methods proportion. For instance, in lesion research, a loss of reorganizationis normally assumed: All different neural regions in a lesioned brain are assumed to be appearing theidentical obligations they executed previous to lesion acquisition, and now not obtaining the features of thelesioned location. (This assumption nearly absolutely does no longer preserve in persistent-level lesionsufferers; Farah, 2004.) In useful imaging research, it is assumed that duties that fluctuate theoretically in aunmarried cognitive technique do now not differentially recruit neural regions for theoretically sharedchallenge components (Posner, Petersen, Fox, & Raichle, 1988). (This assumption is likewise not going tomaintain; Friston et al., 1996.) In addition to these shared inferential troubles, there is an important differenceinside the forms of inferences that may be drawn from useful imaging and lesion methods. In evaluation to
