Arena-based place avoidance on a rotating arena in Darkness and in Light. (A) Arena-Dark place avoidance posed no demand for coordination because the irrelevant room stimuli were hidden by darkness. MK-801 transiently increased locomotion in Darkness on day 1. (B) Arena-Light place avoidance with high demand for coordination due to interference from irrelevant room cues In contrast to darkness, MK-801 markedly and persistently impaired all place avoidance measures in Light. All rats improved their performance during training. *Significant effects of treatment; #significant effect of treatment × session interaction.
