Hello @charlotte2017,

Welcome to Connect.
I could not find any Connect members who have had this procedure, except for @sun711, who in an older post mentioned undergoing a trial with a neurostimulator for occipital nerve pain.

However, I did find this article in one of the journals, which you might wish to view:
Critical review of the responsive neurostimulator system for epilepsy: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4598207/

And, here is a Mayo Clinic update on responsive neurostimulation for epilepsy:
http://www.mayoclinic.org/medical-professionals/clinical-updates/neurosciences/responsive-neurostimulation-for-epilepsy

@charlotte2017, would you share a few more details about yourself? Do you suffer from epilepsy and seizures?
