Speed of movement of the head direction cell activity packet during testing in the absence of visual input with removal of rotational velocity cells.

The results are taken from five simulation runs of a model implemented with of the rotational velocity cells randomly deleted after training had taken place. For each of the five simulations, the exact rotational velocity cells that were deleted were different, i.e. the random selection process was reset with a different seed for each simulation. The table inlines the mean speed of the activity packet across the five simulations during testing as calculated according to equations (14) and (15), the standard deviation, and the mean speed of the packet as a percentage of the speed of rotation of the agent during training in the presence of visual input. In each case, results are inlineed for both clockwise and counter-clockwise rotation of the activity packet during testing.
