Lesley McClurg, writing for KQED Science:
The San Francisco Giants, with the worst record in the National League, could probably use a shot of electricity about now.
Actually, they’re already getting a shot of electricity—literally.
A third of the team is using tDCS headsets, which deliver an electric current to the brain in order to improve performance, says the Giants’ official sports scientist.
The Giants are playing terribly (11–22 thru 33 games) so far this season. If they turn it around, maybe we'll be able to attribute their better play to this electric shock therapy.
