Figure 1: Behavioral testing preparation.

Figure 1:

(A) Open-field-testing arena assembly with part A corresponding to the inner wall, part B as the outer wall, and part C as the base. The finished arena will have two outer walls (parts B) that run the entire edge of the base and two inner walls (parts A) that fit between the outer walls on the adjoining edges of the base (part C). All walls will rest on top of the base. (B) Representative arrangement of arenas on a 0.62 m high table, 60 × 90 cm environmental cues, lights, and a camera for a testing area that allows the capture of all four arenas simultaneously. (C) A curtain hides the experimenter and computer system from mice during trials. The overhead lights are on for the purposes of taking this photograph, but during testing, only the floor lamps are on. Also, one of the environmental cues has been removed for this photograph of the testing area, but during testing, there is a fourth cue in front of the arenas, facing the all black cue behind the table. (D) A representative object (and ruler for scale) that is appropriate for OLT or NORT testing with mice.
