How does responsive neurostimulation differ from deep brain stimulation for epilepsy?

They differ in where they act and when. Deep brain stimulation for epilepsy sits in the anterior nucleus of the thalamus, a hub through which seizures spread, and stimulates on a fixed schedule whatever the brain is doing. Responsive neurostimulation places its leads at the seizure focus itself, records it continuously and stimulates only when it detects a seizure starting, so the team must first know where seizures begin. The thalamic approach suits seizures whose origin is unclear or widespread, and the responsive one suits one or two well-located foci.
