Protocol Steps
1
Habituation
Place each mouse in the empty arena for habituation
View evidence from paper
“On the first day, each mouse was habituated to the empty arena for 10 min”
2
Familiarization
Present two identical objects symmetrically placed in the arena for exploration
View evidence from paper
“On the second day, two identical, previously unfamiliar objects were placed symmetrically relative to the center of the arena, and the mouse was allowed to explore them for 10 min”
3
Testing phase
Replace one familiar object with a novel object and record exploration behavior
View evidence from paper
“On the third day, one of the familiar objects was replaced with a novel object differing in shape, material, or color, and the exploration time of both objects was recorded for 10 min”
4
Arena cleaning
Clean arena between test sessions
View evidence from paper
“The arena was cleaned after each test session”
