In 2017, scientists officially confirmed a mechanism for active forgetting, called essential forgetting. This mechanism involves a subset of specific cells inside the brain and temporarily calls these cells as amnestic cells. They can break down the blots in memory cells.
Similar to fruit flies, dopamine in our body also plays a dual role, which helps both memory formation and forgetting. After a new memory is formed, the dopamine-based forgetting mechanism will begin to erase it.
This erase phenomenon occurs because the cells reverse the structure that created the memory footprint. This is because the natural tendency of cells is to return to the state they had before they learned the memory, unless the brain thinks that this memory is important and it is necessary to preserve it.
After this, such memory imprints are preserved by some consolidation process.Down, there is a balance between remembering and forgetting.
The simple understanding is that when this preset mode encounters some information that is worth remembering for a long time, it will tell the brain to ignore the forgetting process. In this sense, if the brain does not forget, then we will not have a really good memory at all.
After all, compared with the uncomfortable feelings of remembering things, forgetting the useless things is the real torture.
