emotional effects of memories may be reduced, not that the memories are erased.

The research has caused a great deal of argument. Some think it is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories.

“Some memories can ruin people's lives. They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions,” said Roger Pitman, a professor of psychiatry at Harvard Medical School.“This could relieve a lot of that suffering.”

But those who are against the research say that changing memories is very dangerous because memories give us our identity. They also help us avoid the mistakes of the past.

“All of us can think of bad events in our lives that were horrible at the time but they can make us who we are. I'm not sure we want to wipe those memories out,” said Rebecca Dresser ,a medical ethicist.
