Reconsolidation is a biological process that occurs when a previously consolidated memory is reactivated. This reactivation triggers a temporary labile state in the memory, making it susceptible to modification. During this labile period, the memory can be updated with new information, strengthened, or weakened. Following this period, the memory undergoes a new process of stabilization, referred to as reconsolidation. This mechanism is crucial for memory updating and flexibility, allowing organisms to adapt their behavior based on current experiences and learned information.

The process of reconsolidation involves several molecular and cellular mechanisms, often involving protein synthesis and synaptic plasticity. When a memory trace is recalled, it is thought to trigger a cascade of molecular events that temporarily destabilize the neural connections representing that memory. This destabilization allows for the integration of new data or contextual information associated with the reactivation. Subsequently, these changes are stabilized through a process that resembles the original consolidation, solidifying the modified memory.

Research into reconsolidation has significant implications for understanding learning, memory, and even treating conditions like post-traumatic stress disorder (PTSD). By interfering with the reconsolidation process, it may be possible to weaken or modify traumatic memories. This area of study continues to be an active field of neuroscience research, exploring the precise molecular pathways and the full extent of its functional relevance.
