Neuromodulation is the key, not measurements only.
"We were shocked by the results and how quickly the effects of the stimulation could be reversed," says Reinhart.
While these initial results so far are interesting, researchers have a long way to go to see if these brain sync boosts can be scaled up and are safe enough to be used in the long term, or indeed if they apply beyond the simple task of pressing a button every 1.7 seconds.
But even though it's early days, the potential is intriguing.
Conditions like anxiety, Parkinson's, autism, schizophrenia, ADHD, and Alzheimer's all show signs of disrupted brain oscillations, and a treatment like this could help, as well as being more precise in focus than existing drugs.
