Scientists Reveal How the Brain Maintains Useful Memories
[Source: Medical X-Press]
Researchers from the University of Toronto, Canada, have discovered a reason why we often struggle to remember the smaller details of past experiences.
Writing in the journal eLife, the team found that there are specific groups of neurons in the medial prefrontal cortex (mPFC) of a rat’s brain – the region most associated with long-term memory. These neurons develop codes to help store relevant, general information from multiple experiences while, over time, losing the more irrelevant, minor details unique to each experience.
The findings provide new insight into how the brain collects and stores useful knowledge about the world that can be adapted and applied to new experiences.
