[Oooh, induced neuroplasticity? Hell yeah! -egg]

Research had previously shown that adult mice given histone-deacetylase inhibiting drugs (HDAC inhibitors) could “establish perceptual preferences that are otherwise impossible to acquire after youth.” To test whether this connection also existed in humans, Valproate, another HDAC inhibitor, was given to a group of healthy young men with no musical training. The men were then asked to perform a set of exercises for two weeks with the aim of improving their pitch while another control group was asked to perform the same exercises, but given a placebo.

According to the study, those subjects given valproate learned to identify pitch “significantly better than those taking the placebo.” Hensch calls the results remarkable, telling NPR that until now there had been “no known reports of adults acquiring absolute pitch.” The implications of the study aren’t limited to learning how to sing beautifully: by altering brain plasticity, users of valproate could conceivably learn other skills normally picked up during the early critical period. Hensch picks out language learning as an obvious area of application for the drug.
