- Implantable cortical stimulation
The new(er) kid on the block is obviously Implantable cortical stimulation, the author writes about this technique:
Another early-stage investigational technology takes vagus nerve stimulation a step farther. Instead of delivering electrical pulses to a nerve, it sends them to the surface of the brain. Seattle-based Northstar Neurosciences is testing a system that, like vagus nerve stimulation, inserts a pulse generator in the patient's chest. An electrical lead is passed into the skull through a surgically drilled hole, terminating on the dural membrane over the cortex.
