How Brain Stimulation Could Impact How We Develop New Skills

Ned Jenkinson of the University of Birmingham and Matthew Weightman of the University of Oxford discuss how advancements in brain research might affect how we learn and grow our skillsets.
Whether learning a new piano piece or adapting your tennis serve, acquiring physical skills depends on your brain's ability to strengthen and refine neural connections. Researchers are exploring whether this process can be accelerated with technology.
Scientists are particularly interested in the potential of non-invasive brain stimulation, a group of techniques that can alter brain activity without surgery.
Some deliver weak electrical currents to the brain through electrodes placed on the scalp. Others use magnetic fields or focused ultrasound waves. Although they work in different ways, they all aim to temporarily change the activity of neural circuits.
If these techniques can successfully enhance neuroplasticity, the brain's ability to reorganise and form new connections during learning, then they could be of use anywhere where performance depends on learning complex movements, from sport and music to surgery and beyond. Researchers are also seeing if these technologies could help with learning non-physical skills, such as picking up a foreign language.
Elite sport, professional gaming and high-performance workplaces could all become targets for these enhancements if they prove effective. Brain stimulation could also have a big role to play in medicine, helping patients recover physical skills lost through injury or disease, such as stroke.
Studies suggest there's a lot of potential here. But translating this potential into useful tech that reliably boosts learning physical skills remains a big challenge.
Research into enhancing motor learning with electric or magnetic stimulation has been gaining momentum since the turn of the millennium, with early studies garnering considerable excitement.
In a typical experiment, participants might learn a sequence of finger movements similar to practising scales on a piano while receiving stimulation over brain regions involved in movement. Other studies have examined how stimulation could be used for balance training or teaching sports-related skills or surgical techniques.
Some of these experiments produced eye-catching results, finding that participants learned certain movement tasks faster or retained skills for longer if they underwent brain stimulation. But other studies failed to find benefits. And in some cases, researchers struggled to replicate the success of earlier promising experiments when repeating them.
One reason for these mixed findings is that there's no such thing as a universal learning network' in our brains. Different skills rely on different combinations of areas near the surface of the brain as well as those deep within it.
Additionally, people can respond very differently to the same stimulation. Factors such as age, anatomy, genetics and even baseline skill level may influence whether stimulation is beneficial. Add to that the infinite number of ways to apply stimulation, the picture becomes murkier.
