Professor Karim Nader explains that long-term memories are traditionally thought of as being fixed in the brain.
For as long as there is a theory of memory consolidation, people have thought that initially when we acquire new memories, they are in a very dynamic state and sensitive to disruption. But over time, memories were thought to be fixed in the brain. Once memories were fixed in the brain, they were thought to stay in the brain. And so, the current models of memory would say yes, once you have a long-term memory, then that information, wherever it is stored, is going to remain there for the rest of your life.

1236. Memory Disruption
Professor Karim Nader explains that short-term memories are more sensitive to disruption than long-term memories.
1238. Fear Learning
Professor Karim Nader explains that fear learning, which is mediated by the amygdala, is different from other forms of learning.
1235. Memory Re-consolidation
Professor Karim Nader discusses a theory known as reconsolidation, which posits that when a memory is re-activated, it is subsequently re-stored.
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.
1240. Striatum and Memory
Professor Karim Nader explains that the striatum is important to learning motor tasks, such as driving or bike-riding.
1237. Memory and Sleep
Professor Karim Nader discusses evidence that deep sleep can benefit learning motor skills such as riding a bike.
850. Beating Stressful Memories
New research showing how memories take shape may lead to better treatments for unwanted memories as well.
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.
1720. Training Flies
Many of the genes important for memory in flies are probably also important for memory in other animals, even humans. Doctor Josh Dubnau explains how the T-maze is used to test memory in flies.
