Recent animal experiments show that the application of an electrical stimulus to the amygdala or hippocampus following the kindling stimulus produced a significant and long-lasting suppressive effect on this experimental model of epilepsy. This is a preliminary report on the development of a surgical neuromodulatory procedure by chronic electrical(More)
OBJECTIVE In the treatment of tremor and rigidity in patients with Parkinson's disease (PD), the prelemniscal radiation (RAPRL), a subthalamic bundle of fibers, is an exquisite target that can be visualized easily on ventriculograms. We sought to evaluate the effect of electrical stimulation of the RAPRL on symptoms and signs of PD in a long-term trial and(More)
PURPOSE To investigate the clinical, electroencephalographic (EEG), and histopathologic effects of subacute electrical stimulation of the hippocampal formation or gyrus (SAHCS) on 10 patients with intractable temporal lobe seizures. METHODS Bilateral, depth, hippocampal or unilateral, subdural, basotemporal electrodes were implanted in all 10 patients for(More)
Motor cortex stimulation (MCS) is useful to treat patients with neuropathic pain syndromes, unresponsive to medical treatment. Complex regional pain syndrome (CRPS) is a segmentary disease treated successfully by spinal cord stimulation (SCS). However, CRPS often affects large body segments difficult to cover by SCS. This study analyzed the MCS efficacy in(More)
OBJECTIVE To present a review of evidence for an inhibitory thalamo-orbitofrontal system related to physiopathology of major depression disorders (MDDs) and to postulate that interfering with hyperactivity of the thalamo-orbitofrontal system by means of chronic high-frequency electrical stimulation of its main fiber connection, the inferior thalamic(More)
Neuromodulation of the inferior thalamic peduncle is a new surgical treatment for major depression and obsessive-compulsive disorder. The inferior thalamic peduncle is a bundle of fibers connecting the orbito-frontal cortex with the non-specific thalamic system in a small area behind the fornix and anterior to the polar reticular thalamic nucleus.(More)
OBJECTIVE Tremor and rigidity have been efficiently controlled by electrical stimulation of contralateral prelemniscal radiations (Raprl) in patients with unilateral Parkinson's disease. The present study determines the effect of bilateral Raprl electrical stimulation in a group of patients with severe bilateral tremor, rigidity, and bradykinesia. METHODS(More)
PURPOSE Our aim was to evaluate the safety and efficacy of electrical stimulation of the hippocampus in a long-term follow-up study, as well as its impact on memory performance in the treatment of patients with refractory mesial temporal lobe epilepsy. METHODS Nine patients were included. All had refractory partial complex seizures, some with secondary(More)
Incremental, desynchronizing and spike-wave electrocortical responses and concomitant symptoms to acute electrical stimulation of the centromedian thalamic nucleus (CM) were studied in 12 patients with intractable complex partial and tonic-clonic generalized seizures. Low-frequency (6/s), 320-800 microA stimulation of the caudal-basal and central portions(More)
Electrical stimulation of the centromedian thalamic nucleus (ESCM) has been used in cases of difficult to control seizures with multifocal onset in frontal and temporal lobes, as well as in cases of seizures with no evidence of focal onset, such as Lennox-Gastaut syndrome. The stimulation program consists of 1 min stimulation on one side, 4 min interval OFF(More)
