ABSTRACT
Neuroscience.—Building a model of the normal cognitive system is the main goal of cognitive neuroscience. It is widely agreed today that cognitive activities like language and perception (→LANGUAGE, PERCEPTION) are not global, undifferentiated activities but, on the contrary, are made possible through the operation of multiple subsystems, each performing an elementary process. To build a model of cognitive functioning, one must identify these processes and define how the appropriate subsystems are organized and interrelated in order to accomplish a given cognitive operation. The model thus describes a set of subsystems organized into a functional architecture (→COMPUTATIONAL ANALYSIS, FUNCTION).
