Implanted Devices Detect High-Risk Heart Failure Patients

...lity of already weakened heart muscle. Second, the defibrillator "shocks" the heart back into normal rhythm whenever the heart beats irregularly. In addition to maintaining the heart, the devices also collect heartbeat-by-heartbeat data that can be downloaded from the device and entered into a computer. One use o...

MIT: Pulsing light silences overactive neurons

...ly give their brains an electric jolt, acting as a defibrillator to shut down overactive neurons. This new research opens up the possibility of an optical implant that could do the same thing, using light instead of electricity. The Media Lab neuroengineering group plans to start studying such devices in transgeni...
