Table 1.

Tasks simulated in the model. In all experiments, contexts are referred to as A and B, cues as X. “AX-” means X is presented in context A with no US, while AX+ means X is presented in context A with the US in the same trial. ‘;’ separates different trials in the same phase. In each of these phases, the corresponding context is presented to the network by itself before cue presentation mimicking the presence of animal inside a box (see Experimental Procedure).

Simulation	Phase 1	Phase 2	Phase 3
Fear conditioning and extinction	AX+	AX−
Extinction in a new context	AX+	BX−
Renewal	AX+	BX−	AX−; BX−
Reacquisition	AX+	BX−	AX+, BX+
