Object recognition memory. Test phase (30 min after first object exposition) and late test phase (24 hours after first object exposure) refers respectively to equivalents of short term (A, B and C) and long term memory (D, E and F). SAL+ SNP and SAL + MB showed impaired short term object recognition memory. KET + SAL and SAL + KET animals showed impaired short and long term memory when compared to SAL + SAL (#: p < 0.05). Long term memory improvement was seen in KET animals post-treated with GTN and with SNP, but not on those pretreated. Long term memory improvement was seen in KET animals pretreated with MB, but not on those post-treated. *: p < 0.05; **: p < 0.01; tr: p = 0.05. Values presented as mean ± standard error of mean. N = 12 to 14 on each group.
