Abstract. Prefrontal cortex (PFC) has been implicated in the ability
to switch behavioral strategies in response to changes in reward contin-
gencies. A recent experimental study has shown that separate subpop-
ulations of neurons in the prefrontal cortex were activated when rats
switched between allocentric place strategies and egocentric response
strategies in the plus maze. In this paper we propose a simple neural-
