neural circuits. Indeed, it is able to even be the case that the identical population of neurons can guidedifferent cognitive features. Thus, activity of a location in two or greater obligations, or impairment onmultiple tasks because of a unmarried, small lesion, might be defined either by way of a not unusualunderlying function or by using multiple features (Duncan & Owen, 2000; Farah, 1994; Shallice, 1988;Rumelhart & McClelland, 1986). Finally, each lesion technique and practical imaging percentage a relianceon ceteris paribus assumptions: that a unmarried variable is being manipulated and all other matters areequal. Ceteris paribus assumptions create troubles which might be method-particular, but the underlyingphilosophical trouble is one that every one techniques percentage. For example, in lesion studies, a loss ofreorganization is typically assumed: All different neural areas in a lesioned brain are assumed to be acting theequal tasks they completed prior to lesion acquisition, and now not acquiring the functions of the lesionedlocation. (This assumption almost honestly does no longer maintain in continual-degree lesion patients;Farah, 2004.) In practical imaging studies, it is assumed that two obligations that range theoretically in asingle cognitive system do no longer differentially recruit neural areas for theoretically shared task additives(Posner, Petersen, Fox, & Raichle, 1988). (This assumption is likewise not going to keep; Friston et al.,1996.) In addition to those shared inferential issues, there is an important distinction inside the kinds ofinferences that can be drawn from functional imaging and lesion strategies. In assessment to lesion research,
