Functional interactions during the retrieval of conceptual action knowledge: an fMRI study.

abstract：:A task that has been intensively studied at the neural level is f lutter discrimination. I argue that f lutter discrimination entails a combination of a temporal assignment problem and a quantity comparison problem, and propose a neural network model of how these problems are solved. The network combines unsupervised ...
