Professor Karim Nader discusses a theory known as reconsolidation, which posits that when a memory is re-activated, it is subsequently re-stored.
So past theories of consolidation have suggested that once a memory is stored in the brain, it remains fixed in the brain. We and others have found that when a memory is reactivated, when you remember something that is fixed in the brain, it has to undergo another re-storage process. We know that it's not identical to the initial consolidation but nonetheless it is seen in many memory systems.

1236. Memory Disruption
Professor Karim Nader explains that short-term memories are more sensitive to disruption than long-term memories.
1233. Hard-wired Memories
Professor Karim Nader explains that long-term memories are traditionally thought of as being fixed in the brain.
1234. Memory Consolidation
Professor Karim Nader explains that consolidation is a theory of memory that attributes memory formation to changes in synaptic strength and efficiency.
1239. Hippocampus and Conscious Memory
Professor Karim Nader explains that different brain regions are responsible for different types of memory. The hippocampus mediates conscious memory.
850. Beating Stressful Memories
New research showing how memories take shape may lead to better treatments for unwanted memories as well.
1240. Striatum and Memory
Professor Karim Nader explains that the striatum is important to learning motor tasks, such as driving or bike-riding.
1238. Fear Learning
Professor Karim Nader explains that fear learning, which is mediated by the amygdala, is different from other forms of learning.
1237. Memory and Sleep
Professor Karim Nader discusses evidence that deep sleep can benefit learning motor skills such as riding a bike.
1432. Stages of Memory
Doctor Josh Dubnau explains that memories seem to be formed in different stages that evolve over time. These include acquisition, short-term storage, and consolidation.
The hippocampus is closely aligned to memory formation. It is an important early storage place for long–term memory, and is involved in the transition to more enduring permanent memory.
