Analysis of locomotor activity.

<p>Plots of velocity (cm/min) versus time (min) for 60 min activities in large (open circles) and small arenas (solid circles) for: (A) CS male; (B) w1118 male; (C) CS female; and (D) w1118 female. Symbols and lines indicate means ± SE (n = 9 for large arenas; n = 8 for small arenas). Linear regression lines have been superimposed on the data to show the trend of locomotor velocity over time. <i>P</i> values indicate statistical comparison between large and small arenas. Only <i>P</i> values <0.05 are shown.
