Researchers and clinicians are starting to develop methods to change how the brains of young people work. What are the implications of these advances?

The brain stimulation techniques of TMS or tDCS have been used in adults, but less frequently in children. Swansea Psychology Lecturer Dr Nick Davis was interviewed in this week's Nature magazine. "Brain stimulation in children is potentially very exciting for treating disorders such as dyslexia or low intellectual attainment. But we must be cautious because there are some risks with TMS and tDCS that we are only beginning to understand," he explained.
