The Parietal Cortex in Sensemaking: The Dissociation of Multiple Types of Spatial Information
Figure 11
The dissociation and interference between numerosity and size. (a) A visual input with high numerosity but small patch size. (b) A visual input with low numerosity but large patch-size. (c) Without top-down control and teaching signals, units on the same hidden layer show sensitivity to either numerosity (left panel) or size (right panel), or both (the overlap of unit locations). Sensitivity is measured by in a linear regression of the activation on the respective magnitude.
