Scientists may have discovered more details about how memories work and how our brain stores them and plays them back to us.
The study says that brains cells referred to as “boundary” and “event” cells are responsible for marking specific memories in our brains. As such, it means that our brains may treat each memory as its own object. Essentially, your memories can be thought of as files inside a filing cabinet.
These boundaries are thought to trigger changes in how a memory is stored, as well as how our brains mark the beginning and end of the memory “files” that it stores. The researchers hoped it would give them a solid look at how memories work. They showed the patients two types of clips, which they referred to as “soft” and “hard” boundaries.
They looked at the brain activity recorded during each transition to see how the brain would handle it. Boundary cells reacted to both hard and soft boundaries. However, the event cells only responded to hard boundaries. This showcased the different parts that each cell plays in how memories work.By looking at the triggers and the cell types used in each boundary trigger, the researchers were able to determine a bit more about how memories work in our brains.
