Systemic corticosterone administration impairs the late fear memory reconsolidation via basolateral amygdala glucocorticoid receptors: Dependence on the time window and memory age

•Systemic injection of corticosterone (10 mg/kg, i.p.) 12 h after memory reactivation impaired the memory reconsolidation in an inhibitory avoidance task.•This effect was observed on 2-day-old memory but not 7, 14, 28, and 56-day-old memories.•GRs in BLA are involved in corticosterone-induced memory impairment.•Memories become more resistant to disruption in an age-dependent manner.
