Abstract:
ObjectiveTo investigate the relationship between novelty seeking and impulsivity behavior in rats.MethodsTwo models were used to test Novelty seeking,one was activity in a new environment model,the other was novel object preference model.And impulsivity was measured by T-maze.All rats(48) were used to examine the relationship between these two behaviour traits.ResultsNovelty seeking:the locomotor activities measured in a new environment for 30 min were (4695.58 ± 1579.87)cm,the exploring number of entries into the novel object area and time spending in the novel object area were respectively(20.92 ± 14.84)entries and (178.12± 135.22)s.Impulsivity:the average times of choosing low reward(LR) in the two test days were(4.71 ±2.71 ).Pearson product moment correlation was performed to investigate the relationship between these two behaviour traits,and the results suggested that there were notable correlation between novel object preference and impulsive decision making( r =0.295,P＜ 0.05 ),yet no significance were found between new environment activity and impulsive decision making.ConclusionNovelty seeking and impulsivity may be correlated with each other depending on different models.
