Cognitive conjunction and cognitive functions.
We argue that conjunction analysis does not solve the problems with subtraction analyses that it sets out to solve and that it has additional problems of its own. We argue that detailed analyses of the tasks set to identify cognitive functions are required for both conjunction and subtraction analyses to achieve their goals of localizing cognitive operations using functional neuroimaging techniques.
