Neurobiological models of long-term memory propose a mechanism by which initially weak memories are strengthened through subsequent activation that engages common neural pathways minutes to hours later. This synaptic tag-and-capture model has been hypothesized to explain how inconsequential information is selectively consolidated following salient experiences.  
Behavioural evidence for tag-and-capture is provided by rodent studies in which weak early memories are strengthened by future behavioural training. 

Whether a process of behavioural tagging occurs in humans to transform weak episodic memories into stable long-term memories is unknown. Here we show, in humans, that information is selectively consolidated if conceptually related information, putatively represented in a common neural substrate, is made salient through an emotional learning experience.

Commentaar 
Wat ik niet goed begrijp aan dit onderzoek aan New York University is dat eerst proeven gedaan worden met knaagdieren (‘rodent studies’). En daarna doen ze het dan nog eens dunnetjes over met menselijke proefpersonen. Het zal wel naïef zijn maar ik zou toch wel willen weten wat knaagdieren hiermee te maken hebben. En daar krijg je dan weer geen antwoord op...
