Deep-brain Magnetic Stimulation (DMS) is a noninvasive brain modulation method that improves hippocampal neural activity. The frequency of DMS has significant effect on the induced electric field. In this paper, we investigate relationship between stimulation and DMS-induced sensitivity distribution uniformity field are calculated to quantify relationship. results show frequency-dependent prope...

Abstract Stimulation of axons or its avoidance plays a central role for neuroprosthetics and neural-interfaces research. One peculiar example constitutes retinal implants. Retinal implants aim to artificially activate ganglion cells (RGCs) via electrical stimulation. Such stimulation, however, often generates undesired stimulation RGC axon bundles, which leads distorted visual percepts. In orde...

The left posterior inferior frontal gyrus in the prefrontal cortex is a key region for phonological aspects of language processing. A previous study has shown that alpha-tACS over applied before task processing facilitated decision-making and increased task-related theta power. However, it unclear how affects when directly during task. Moreover, frequency specificity this effect also since majo...

Brain stimulation is a promising therapy for several neurological disorders, including Parkinson's disease. Stimulation parameters are selected empirically and are limited to the frequency and intensity of stimulation. We varied the temporal pattern of deep brain stimulation to ameliorate symptoms in a parkinsonian animal model and in humans with Parkinson's disease. We used model-based computa...

Introduction: Low-frequency stimulation (LFS) has a delaying effect on kindled seizures acquisition. In the present study we examined the role of galanin receptors in the inhibitory effects of LFS on kindled seizures induced by electrical stimulation of perforant path. Methods: Animals were stimulated daily at the AD threshold intensity with a rapid kindling procedure. LFS was applied immed...

OBJECTIVE To evaluate the suppressive effect of electric cortical stimulation upon the seizure onset zone and the non-epileptic cortex covered by subdural electrodes in patients with neocortical epilepsy and mesial temporal lobe epilepsy (MTLE). METHODS Four patients with medically intractable focal epilepsy had implanted subdural electrodes for preoperative evaluation. Cortical functional ma...

BACKGROUND Based on the basal ganglia model, it has been hypothesized that the efficacy of high-frequency stimulation of the subthalamic nucleus (STN) against parkinsonian symptoms relies on the activation of cortical premotor regions. In previous positron emission tomography activation studies, STN high-frequency stimulation was associated with selective activation of midline premotor areas du...
