Brain stimulation can rewire and heal damaged neural connections, but it isn't clear how – research suggests personalization may be key to more effective therapies

The connections between the neurons in your brain enable you to do amazing things, from brushing your teeth to solving calculus equations. When these connections become damaged, often as a result of conditions like stroke or traumatic brain injury, these abilities can be lost. Directly activating neurons with tiny pulses of electricity, however, can help rewire these connections and potentially restore function.

Doctors currently use this technique, called neurostimulation, to treat conditions like Parkinson’s and depression. We believe that neurostimulation has the potential to not only treat symptoms but also cure a wider range of diseases by repairing damaged connections. However, it has been unclear how to best fine-tune stimulation to specifically target damaged connections within the brain.
