Researchers have developed a device that works like a "pacemaker for the brain" to monitor the brain's electrical activity and potentially deliver fine-tuned treatments to patients with diseases like epilepsy and Parkinson's. The device is short for wireless artefact-free neuromodulation device, can deliver electrical stimulation if it detects something amiss in the brain's electrical activity. The device is both wireless and autonomous, meaning that once it learns to recognise the signs of tremor or seizure, it can adjust the stimulation parameters on its own to prevent unwanted movements.

And because it is closed-loop -- meaning it can stimulate and record simultaneously -- it can adjust these parameters in real-time. "We want to enable the device to figure out what is the best way to stimulate for a given patient to give the best outcomes. And you can only do that by listening and…
