A simplified schematic of the interactions between memories during consolidation. a New learning (training 2) during a lapse point leads to the disruption of the first memory (retroactive interference) regardless of the whether the new memory is encoded within the same of a different circuit as the first memory. b When new learning occurs during a non-lapse point of the first memory and both memories are encoded in the same circuit, the first memory is retained and the second not acquired (proactive interference). c Acquisition of a second memory at a non-lapse point that activates a different circuit from the one triggered by the first learning does not lead to proactive interference and allows dual memory consolidation
