Definition: The zones (A, B and C) are defined by two concentric circles between the center and edge of the water maze pool. Zone A is the area within the smallest circle, Zone C is that between the larger circle and the pool edge, and Zone B is the area between the two. In HVS Image systems the zones may be set as equi-distant, in which case the divisions between each zone are one third of the pool radius apart, or equi-area, in which case the divisions between zones are such that the zones have the same area as each other. These circular zones are sometimes referred to as radii (or radiuses).
