Abstract
This is directed to a neurostimulator assembly that is preferably implantable and is suitable for treating epilepsy and other neurological disorders. The assembly includes inventive leads that are suitable both for providing electrical somatosensory stimulation, extradurally applied, as well as electrical stimulation that is applied to the central nervous system. The leads are preferably also suitable for sensing electrical signals in the brain. The invention includes processes of using the neurostimulator and its leads. The neurostimulator may independently provide a variety of different electrical stimulation, e.g., non-responsive electrical stimulation signals applied to the central nervous system to reduce the likelihood of a seizure or other undesirable neurological even from occurring, electrical stimulation signals applied to the central nervous system when the neurostimulator determines that epileptiform waveforms are impending or extant, and extradural electrical somatosensory stimulation signals. The responsive electrical stimulation signal or signals are intended to terminate epileptiform activity, e.g., to desynchronize abnormally synchronous brain electrical activity.
