Scientists have developed a device named WAND which stands for "Wireless artifact-free neuromodulation device" that works like a "Pacemaker for the brain" to monitor the brain's electrical activity and potentially deliver fine-tuned treatments to patients suffering from diseases like epilepsy and Parkinson's. The most important feature of the device is that it is both wireless and autonomous, which means when it learns to recognize the signs of tremor or seizures then it can adjust the stimulation parameters on its own to prevent the unwanted movements. The device has custom integrated circuits to record the full signal from both the subtle brain wave and the strong electrical pulses.
