Theoretical background:

For information on head direction, please refer to the head direction page or to the papers listed in the Hippocampus and Navigation Group homepage.

The head direction code ...

In the WG model, the head direction perceptual schema projects to its respective feature detector layer, the head direction code. In the figure shown below, this layer is composed of 400 nodes which are organized in a two dimensional matrix. The different colors represent the amount of activity being received in each cell of the matrix. Each node in the head direction perceptual schema connects to all nodes in the feature detector layer, i.e., the two are fully connected.
