A major challenge for any attempt at combining linguistics with empirical neurophysiological data from brain research, like ERPs for example, is to give an answer to the question of how the gap between psycholinguistic and formal models of specific aspects of language on the one hand and the neural architecture underlying neurophysiological measures on the other can be bridged (Baggio et al. 2010 ). An interesting research program based on the extension of the event calculus in Van Lambalgen &

In this paper we will present an alternative formal theory which is based on the technique of combining systems and in which the dynamics of information change is separated from the more static aspects of knowledge representation. Using this multi-layered architecture, we hypothesize that the LAN is related to the process of updating a discourse model in the light of new information about changes in the world whereas the N400 concerns the more static aspects of situation models, e.g. the relation between events and persistent objects. 1
