Behavioral phenotyping has been gaining prominence due to the increased use of transgenic animal models of neurological disorders. Repeated testing in the same cohort of animals can reduce the overall number of animals used and is desired especially when animal numbers are difficult to obtain as well as for studies involving within-subject design such as drug treatments or aging. This review aims to provide researchers with a comprehensive overview of the carryover effects when subjecting the same set of animals to the same behavioral test. We have focused on three behavioral domains of testing: anxiety, cognition and depression. Based on a review of the literature and our own experiences as a neurobehavioral core facility, we have found that manipulating inter-test interval, environmental contextual cues and stimuli can mitigate the carryover effects to a large extent, although there are certain tests that still show strong residual effects. In addition, the effects of strain on carryover effects from repeated testing are also discussed in this review. |
