Supplementary Fig. 2: A positive need term is required for sequential value propagation.
From: Prioritized memory access explains planning and hippocampal replay
(a) Number of significant forward and reverse sequences on linear track (left) and on open field (right) when setting the need term to the Successor Representation (as predicted by the theory). (b) Number of significant forward and reverse sequences on linear track (left) and on open field (right) when setting the need term to be one at the agent’s location and zero elsewhere. Notice the complete absence of both forward and reverse sequences due repeated replay of actions on the agent’s location.
