What part of the brain is "fake memory" made?

It is known to everyone that what is called "memory mismatch" can happen,You can arbitrarily create fake memoriesRecent studies have found that, but little is known about how false memory is created. A British researcher wonders where false memory comes from the brainFMRII found it in an experiment using.

The research team of Dr. Martin J. Chadwick of University College London investigated how incorrect memory is produced in the brain. Dr. Chadwick tests words, for example, if you select only the words related to the cold, such as "ice (ice)" "snow" "wind", it is listed in the word list I used the fact that subjects tend to misunderstand that words related to the cold "cold" were on the list.

Dr. Chadwick observed the brains of subjects with fMRI when they were causing "memory mismatch" to mistakenly memorized relevant words as in the past. Then, under the situation of "memory mismatch" in which words not listed are "remembered", many overlapping with the activated brain region is observed when recalling other words listed on the list He said that.


In addition, all the subjects commonly observed the fact that the brain region which is in common with the memory associated with them is active when recalling the false memory was commonly observed in all subjects, but the part which is activated for each subject The location of itself was different.

From the above results, Dr. Chadwick concludes that other related memories are involved in the process of false memory being generated, and by remembering different facts and memorizing it, the brain can do a lot of things I am thinking that I remember it efficiently.
