A Blanker Slate

Nick Carr summarizes a new study:

Slowly but surely, scientists are getting closer to developing a drug that will allow people to eliminate unpleasant memories. The new issue of Neuron features a report from a group of Chinese scientists who were able to use a chemical - the protein alpha-CaM kinase II - to successfully erase memories from the minds of mice. The memory losses, report the authors, are "not caused by disrupting the retrieval access to the stored information but are, rather, due to the active erasure of the stored memories." The erasure, moreover, "is highly restricted to the memory being retrieved while leaving other memories intact. Therefore, our study reveals a molecular genetic paradigm through which a given memory, such as new or old fear memory, can be rapidly and specifically erased in a controlled and inducible manner in the brain."
