Definition: The water maze pool is typically divided for some analyses into four quadrants, NE, SE, SW and NW, with North being the side of the pool at the top of the tracking system video image, and the top of path plots. The percentages of time and/or path spent in the target quadrant are widely used as basic measures of proximity to the target platform position.

HVS Image systems give the percentage time spent in each quad and percentage path in each quad. Quad entries are also used in HVS Image systems to quantify circling in water maze.

First implemented in HVS Image VP110  in 1985
