Abstract
Background: Methamphetamine (MA), is a widely abused synthetic psychostimulant that leads to irreversible brain damage
manifested as cognitive impairments in humans and animals. The novel object recognition (NOR) task is a commonly used
behavioral assay for the investigation of non-spatial memory in rodents. This test is based on the natural tendency of rodents to
spend more time exploring a novel object than a familiar one. NOR test has been used in many studies investigating cognitive
deficits caused by MA in rodents. The objective of the present study was to review neurobiological mechanisms that might be
responsible for MA-induced NOR alterations.
Methods: A PubMed search showed 83 publications using novel object recognition and methamphetamine as keywords in the
past 10 years.
Findings: The present study revealed different MA regimens cause recognition memory impairment in rodents. In addition,
it was found that the main neurobiological mechanism involved in MA-induced recognition deficits is the dysfunction of
monoaminergic systems.
Conclusion: NOR is a useful test to assess the cognitive functions following MA administration and evaluate the efficacy of new
therapeutic agents in MA-addicted individuals.
