The number of entries into the open arm of an elevated plus maze (EPM) (top panel) and the time spent in contact with the novel object during a novelty task (bottom panel) The stressor treatment markedly reduced the number of EPM open arm entries in saline injected mice, but this effect was totally absent in mice that received the EPO treatment.

<p>The bottom panel depicts that a robust stressor-induced reduction of exploration of the novel object was apparent. However, EPO had no influence on this behavioural measure. Data are expressed as mean ± SEM (<i>n</i> = 8/group) *<i>p</i> < 0.05.
