The Parietal Cortex in Sensemaking: The Dissociation of Multiple Types of Spatial Information

Figure 5

Two different configurations for providing the same spatial information to the PC module. (a) Two objects (e.g., a group center and a POI) are presented on the same input layer. (b) The same object pair is presented on two separate layers. When the task is to compute the Euclidean distance (flying distance) between the two objects, these two configurations yield indistinguishable performance. To compare the model performance, we computed the model-target correlation (correlation between the output values at the minus phase and the target values across trials). In both configurations, after training for 1000 epochs (20 trials in each epoch), the model can produce a model-target correlation greater than 0.95 in the last 10 epochs ( trials).
