Abstract

Well-consolidated fear-related memories, once retrieved, are susceptible to disruption and require reconsolidation in order to be maintained. We examined whether reactivated reward-related memories are also susceptible to interference by evaluating the effect of propranolol (PROP), a beta-adrenergic antagonist known to impair reconsolidation of fear-related memories, on context-induced sucrose seeking. PROP administration upon reactivation reduced sucrose seeking behaviour 3 weeks post-training, indicating that reconsolidation of reward-related memories can be disrupted after a long post-training interval.
