Abstract: | Previous studies have explored two-dimensional path integration in rodents by recording responses to passive rotation on
a horizontal plane. This study adds the element of passive rotation in a vertical plane, necessitating the mouse to integrate
positional information from three dimensions. Mice were trained to climb a wire mesh joining two horizontal planes. The whole
arena was rotated 90° while the mouse was vertically oriented as it moved between planes. Rotation was conducted both clockwise
and counter-clockwise, controls being provided by rotation of the arena while the mouse was in its nest-box. All 16 mice tested
altered their direction of travel subsequent to rotation in the vertical plane, compensating with a change in their path on
the following horizontal plane.
