The '''Between-Systems Memory Interference Model''' describes the inhibition of non-hippocampal systems of [[memory]] during concurrent hippocampal activity. Specifically, Fraser Sparks, Hugo Lehmann, and Robert Sutherland<ref>{{cite journal|last=Sparks|first=Fraser|author2=Lehmann H.|author3=Sutherland R.J.|title=Between-systems memory interference during retrieval|journal=European Journal of Neuroscience|year=2011|issue=34|pages=780–786|doi=10.1111/j.1460-9568.2011.07796.x|volume=34}}</ref> found that when the [[hippocampus]] was inactive, non-hippocampal systems located elsewhere in the brain were found to [[Memory consolidation|consolidate]] memory in its place. However, when the hippocampus was reactivated, [[Engram (neuropsychology)|memory traces]] consolidated by non-hippocampal systems were not recalled, suggesting that the hippocampus interferes with [[long-term memory]] consolidation in other memory-related systems.
