Figure 4: DBI−/− mice display impaired performance in the probe trial of the Barnes maze test.
Mean ± SEM of number of nose pokes (visits) into each hole during probe trial. Hole 0 is the target hole, with positive values progressing clockwise from the target hole. Open circles represent individual data values for number of visits to the target hole by each mouse. ****, significant difference between DBI+/+ and DBI−/− mice (P <0.0001)
