From: A neural field model of decision making in the posterior parietal cortex
Activity in the PPC layer of the model. A spatial cue is presented at the probe direction (PD). The remapped direction (RD) is the position that the model previously learned to be the valid goal, when an additional contextual cue was presented. The time axis shows the memory period from onset of the transient spatial cue until just before the goal is to be selected (go cue). When exposed to 80 % remapped motor goals and 20 % direct mapped goals, the model develops a bias towards the remapped direction (RD), when tested in a free choice trial (A). If the ratio is 50/50, both potential motor goals are equally represented (B).
