- The team studied a brain region called the hippocampus, which stores "episodic” memories, which are memories of events or conversations that might be forgotten over time if not used. The challenge to studying synapses in this region is that the hippocampus is so deep that no microscope could easily monitor the synapses' longevity.
- By leveraging microscopy tools, the team was able to push forward. In the mice he and his team studied, the connections between neurons lasted about 30 days, roughly the duration over which episodic memories are believed to stay in the mouse hippocampus.
- Schnitzer said that the work confirmed a long-held idea about how the brain stores memories. Using the same techniques, scientists can now probe additional aspects of how memories are formed, remembered and eventually lost at the level of the individual connections between neurons.
New Study Finds That Brain Connections Last as Long as the Memories They Store
