Beer makes you clever: official | The Register

While this is not exactly about darts it does focus on alcohol consumption (which may or not be involved in darts).

That's to say, a Swedish team has shown that mice fed with moderate amounts of alcohol grew new nerve cells in the brain. The full implications of the Karolinska Institute research - which appears in the International Journal of Neuropsychopharmacology - are unclear, but lead boffin Stefan Brene told the BBC: "We believe that the increased production of new nerve cells during moderate alcohol consumption can be important for the development of alcohol addiction and other long-term effects of alcohol on the brain."

He did, however, add that it's possible that "the extra cells might help with learning and memory" - although we reckon the word "moderate" is key here since no-one who has ever drunk 16 pints of ale has been able to recall a single detail of the session come the following morning.
