Attention ability of rats to recognize a novel object in a habituated open‐field arena tested 5 days after surgery. The time spent with exploration of the novel object in percent of time spent with exploration of both novel and familiar objects is shown. The 50% represents the chance level. Animals with bilateral entorhinal lesion (NMDA) performed worse than sham controls (**P < 0.01) and treatments with vinpocetine (Vinp) and cis‐apovincaminic acid (cAVA) in a dose of 10mg/kg i.p. prevented this deficit (#P < 0.05 and ##P < 0.01 vs. NMDA group, respectively). The numbers of animals per groups are showed inside the columns. Columns represent means ± SEM.
