Protocol Steps
Morris water maze acquisition phase
Mice are trained to locate a hidden platform in the water maze during the acquisition phase
Note: This phase establishes baseline spatial learning ability

“On the Morris water maze task, DBA/2J, AKR/J, BTBR T+tf/J, and 129S1/SvImJ failed to show significant quadrant preference during the reversal probe trial”
Morris water maze reversal phase
The spatial location of the hidden platform is reversed to assess cognitive flexibility and reversal learning ability
Note: Reversal learning measures the ability to adapt to changed environmental contingencies

Reversal probe trial
A probe trial is conducted during the reversal phase to assess quadrant preference and platform location memory
Note: Quadrant preference during reversal probe trial indicates successful reversal learning
