The main aim of this study is a simple question: How does our brain store and organize memories? We live our lives in one continuous way and experience everything coming in between. Researchers believe that we keep life events as individual or distinct moments.
One more question gets linked with brain storage: What is the beginning or end of a stored memory? We know very little about the work process undergoing inside the human brain. This process is also called event segmentation.
To expand the study on this topic, many researchers organize experiments working on 20 patients undergoing intracranial brain recording to guide their surgery for treatment. The research was to keep an eye on the patient's brain function and How it was affected while watching film clips of different cognitive boundary transitions for triggering changes in a stored memory which marks the beginning and end of it in the brain.
The researchers monitor the brain activities of the participants. While the participants watched the video, the researchers noticed two large groups of cells responding differently by increasing their activities. One of these groups was called boundary cells and was more responsive to soft, hard-boundaries. The second one is referred to the event cells as they responded only to the hard ones.
It helped researchers understand, How new memories get created while a peak in the activity of boundary or event cells. This process occurs only after a hard-boundary.
