New research suggests that we remember life like a film

A new study has shed light on just how the brain may process life.  We have known for a long time where memories may be stored, but new research gives us a tantalising glimpse at just how this happens. Publishing in the Journal of Neuroscience, researchers may have just shown us just how ‘Hollywood’ are memories may be.

Built for complexity

The new data, gleaned from hundreds of participants, suggests that the hippocampus (an area of the brain associated with memory,) is able to split information into manageable chunks.

Participants watched films (including Forrest Gump,) whilst hooked up to a functional MRI (which can map brain activation in real-time.) At the same time, 16 observers watched the same film and indicated when they believed that ‘events’ in the film began and ended.

Strikingly, it seemed that the brain was most active at these ‘event points’, suggesting that the entire film was memorised in small sections as opposed to one flowing narrative. All in all, it suggests that our brains process information into workable bits of information, much like a film reel.

Brain built for simplicity

So what does this add to our knowledge? Many theories already suggest that the brain acts as a filter for information, only storing what is important. If we were to take in every small bit of data, we would likely be overwhelmed. This new study shows us that the brain may do this based not just on space, but also the emotive and narrative component of what we see.

It may very much be that memory, like a good film, depends on important and emotive set pieces, with the most important moments given the most weight. And when we already know just how tricky memory can be, we can now ask why the brain chooses as it does.

So what do you think? Is there a reason the brain may work like this? What are the benefits? Let us know in the comments, and if you enjoyed this article please share!

  • Interesting read…would recommend 🙂
    Correct me if I’m wrong but i’m thinking the main reason the brain filters information, would be for the purpose to block out extreme traumatic life experiences.
    The information also poses the curious question (for me at least), the reasons behind why each individual stores information differently, why are certain events more important to one individual yet doesn’t arouse the same interest/curiosity in the next person.
