Memories can be erased and created to some extent researchers purport

Two recently published studies describe scientists implanting fabricated memories and selectively erasing unwanted memories in the brains of lab rodents.

Researchers at UC Irvine have found that by playing a particular tone while stimulating the release of a brain chemical associated with memory formation they can artificially “condition” a response to the tone in lab rats, which is recalled and observable the following day. Fabricated memories have the same features as naturally-occurring memories, Science Daily reports, “including long-term retention.” Researchers say this represents “the first evidence that memories can be created by direct cortical manipulation.”
