Extended Data Figure 6: Vector-based navigation schema.
From: The honeycomb maze provides a novel test to study hippocampal-dependent spatial navigation
Left, The hippocampus represents a goal-direction vector pointing from the rat to the goal (A), which decreases as the rat is farther from the goal (right). The navigation system computes the projection of each choice platform vector (B, C) onto the goal-direction vector (inner product, Bgd, Cgd) and selects the larger of the two. This choice is easier with increased angle between choices (angle β) and consequent increased difference in the magnitudes of their projection vectors. The projection vector of the preferred platform, Bgd, is the output of the system that competes with other potential solutions to the problem (for example, choose between the leftmost or northmost platform).
