The Shuttle Box Test for TDPA, or temporally dissociated passive avoidance, measures hippocampus-dependent associative learning by testing whether a rodent avoids entering a dark compartment that was previously paired with foot shock after a temporal delay between dark-compartment entry and shock delivery. The main behavioral readout is crossover or step-through latency from the light chamber into the dark chamber; increased latency across training or retention trials reflects learned avoidance memory rather than motor performance alone.

The Morris Water Maze is a rodent spatial learning and memory assay in which a mouse or rat swims in opaque water to find an escape platform; in the hidden-platform version, the animal cannot see the platform and must use distal extra-maze cues to learn its fixed spatial location. The assay primarily measures hippocampus-dependent spatial learning during acquisition trials and spatial reference memory during probe trials after platform removal; readouts include escape latency, swim path length, swim speed, quadrant occupancy, platform-site crossings, and proximity to the former platform location.
