Researchers discover mechanism for memory storage in engram cells

Posted by in category: neuroscience

What is the mechanism that allows our brains to incorporate new information about the world, and form memories? New work by a team of neuroscientists led by Dr Tomás Ryan from Trinity College Dublin shows that learning occurs through the continuous formation of new connectivity patterns between specific engram cells in different regions of the brain.

Whether on purpose, incidentally, or simply by accident, we are constantly learning and so our brains are constantly changing. When we navigate the world, interact with each other, or consume media content, our brain is grasping information, creating new memories.

The next time we walk down the street, meet our friends, or come across something that reminds us of the last podcast we listened to, we will quickly re-engage that memory information somewhere in our brain. But how do these experiences modify our neurons to allow us to form these new memories?
