Navigational performance in the virtual audiovisual spatial navigation task.

<p>(A) Schematic of the virtual environment indicating distal auditory and visual cues and a hidden reward zone and the four start locations. (B) Example paths from a single rat from the 1^st session. The color of each path indicates start location, color coded from the arrows in A. (C) Example paths from the same rat from the 6^th session. (D) Acquisition curve of latency to reward across sessions. F(5,35) = 4.266, p = 0.0061, Session 1 vs. Session 3: p<0.05, N = 6. (E) Acquisition curve of the distance traveled to reward across sessions. F(5,35) = 3.00, p = 0.0296, Session 1 vs. Session 5: p<0.05. (F) 2-D histogram of mean occupancy averaged across final four task sessions of asymptotic performance with the smaller reward zone. (G) Example of a probe trial path. (H) Percentage quadrant measures for occupancy time during the final four task sessions performance and during the probe trial. Effect of quadrant: F(3,23) = 10.15, p = 0.007, F(3,23) = 10.9, p = 0.0005, respectively.
