The idea of a simple, cheap and widely available device that could boost brain function sounds too good to be true.
Yet promising results in the lab with emerging ‘brain stimulation’ techniques, though still very preliminary, have prompted Oxford neuroscientists to team up with leading ethicists at the University to consider the issues the new technology could raise.
Recent research in Oxford and elsewhere has shown that one type of brain stimulation in particular, called transcranial direct current stimulation or TDCS, can be used to improve language and maths abilities, memory, problem solving, attention, even movement.
Critically, this is not just helping to restore function in those with impaired abilities. TDCS can be used to enhance healthy people’s mental capacities. Indeed, most of the research so far has been carried out in healthy adults.
