Like everyone, I’ve got my share of bad memories, but would erasing them change me for the worse?
Many of us are the bearers of “bad” memories that, to this day, continue to affect our lives. Now, scientists say they have discovered a gene essential for “memory extinction,” the process by which our brain replaces older memories with new experiences.
Researchers from the Massachusetts Institute of Technology (MIT) say the discovery could help people suffering from post-traumatic stress disorder (PTSD) by replacing “fearful” memories with more positive associations.
The gene, Tet1, has been found to play a critical role in memory extinction by controlling a small group of other genes that are necessary for the process.
For the study, published in the journal Neuron, the research team experimented on mice who had the Tet1 gene “knocked out,” as well as on mice who had normal levels of the gene.
