Most humans can recall specific events and past experiences for long periods of time. This capability, referred to as episodic memory, is known to be in great part supported by the activity of neurons in the hippocampus and medial temporal lobe.

Past neuroscience and psychology studies consistently found that episodic memory is associative. This essentially means that remembering one past event, for instance a graduation, can in many cases prompt people to also remember other related events, such as a party that celebrated the graduation.

Researchers at Biología Molecular y Neurociencias (IFIByNE)-CONICET and the University of Buenos Aires recently carried out a new study exploring the possibility that the reactivation of specific episodic memories does not only help to strengthen those memories, but also the memories of other related events or experiences.
