sang-ayon sa pag-aaral na ito, okey lang ang nakakalimot minsan:
Forgetfulness is a tool of the brain
By Michael Reilly
A note to the forgetful: be thankful you don’t remember everything. It means your brain is working properly.
According to a new study, the brain only chooses to remember memories it thinks are most relevant, and actively suppresses those that are similar but less used, helping to lessen the cognitive load and prevent confusion.
Brice Kuhl at Stanford University in California, US, and colleagues used functional magnetic resonance imaging (fMRI) to measure the brain activity of 20 healthy adults while they performed a simple memory test. Participants were given three words pairs to memorise, including two pairs that were closely associated, as follows:
ATTIC dust
ATTIC junk
MOVIE reel
After studying “ATTIC dust†a second time, subjects were asked to recall all three pairs using the first words as cues. On average, people were 15% worse at recalling “ATTIC junk†than they were at recalling the unrelated pair, “MOVIE reelâ€.
Initial suppression
Comparing these findings to the fMRI data taken during the test, the team found participants’ brains were highly active in a region known for handling competing memories, and also in an area believed to induce memory suppression.
The researchers believe that the first region identified “ATTIC dust†and “ATTIC junk†as conflicting memories. The second region then suppressed “ATTIC junk†because it had only been seen once.
As the test was readministered a second and third time, suppression activity lessened, indicating the memory adjustment had been made.
Prioritising memories
“Whenever you’re engaging in remembering, the brain adapts. It’s constantly re-weighting memories,†says Kuhl. “In this simple test, we see it reverse memory to weaken competing memories. This is something that probably happens a lot in the real world.â€
A good example is the confusion that arises when we change passwords on our computers or email accounts. We often mix up old and new passwords at first, but through repetition we develop a strong memory of the new password and forget the old one.
“The process of forgetting serves a good functional purpose,†says Michael Anderson of the University of Oregon, US, who was not involved in the study. “What these guys have done is clearly establish the neurobiological basis for this process.â€
