Spatial novelty preference. (A) Mean (± standard error of the mean) time spent in the three arms of a y-maze during the test phase of the task. There were no differences between the groups in terms of time spent in the novel or familiar arms. Note that the unoperated (un-op) group spent less time in the start arm than the other two groups, but this was because the un-op group spent more time in the “central area” (i.e., at the choice point). (B) Mean (± standard error of the mean) preference for the novel arm expressed as a ratio (novel/[novel + familiar]). There were no group differences on this measure.
