The effect of High and Low frequency cortical Stimulation with a Fixed or a Poisson Distributed Interpulse Interval on cortical excitability in rats
نویسندگان
چکیده
Neurostimulation is a promising treatment for refractory epilepsy. We studied the effect of cortical stimulation with different parameters in the rat motor cortex stimulation model. High intensity simulation (threshold for motor response--100 μA), high frequency (130 Hz) stimulation during 1 h decreased cortical excitability, irrespective of the interpulse interval used (fixed or Poisson distributed). Low intensity (10 μA) and/or low frequency (5 Hz) stimulation had no effect. Cortical stimulation appears promising for the treatment of neocortical epilepsy if frequency and intensity are high enough.

Effect of different frequencies of repetitive transcranial magnetic stimulation (rTMS) on acquisition of chemical kindling seizures in rats
IIntroduction: Repetitive transcranial magnetic stimulation (rTMS) modulates the excitability of cortical neural networks. The effect of rTMS on excitability of cortical networks depends on its frequency. According to the previous reports, a distinction is made between low (<1Hz) and high frequencies of rTMS. Low frequencies of rTMS inhibit seizure but high frequencies increase it. In the curre...
متن کاملResponses of primary somatosensory cortical neurons to controlled mechanical stimulation.
The results of psychophysical studies suggest that displacement velocity may contribute significantly to the sensation of subcortical somatosensory neurons. The cortical correlates of these phenomena, however, are not known. In the present study the responses of rapidly adapting (RA) neurons in the forelimb region of cat primary somatosensory cortex (SI) to controlled displacement of skin and h...

Motor responses evoked by transcranial magnetic stimulation OMS) or transcranial electrical stimulation (TCS) can be facilitated by a prior conditioning stimulus to an afferent nerve. Two facilitation periods are described short (SI), when the nerve stimulus is given near 0 to 10 ms after cranial stimulation, and long (LI), when nerve stimulation is given 25-60 ms before the cranial stimula...
متن کاملEffects of Cortical and Peripheral Electrical Stimulation on Brain Activity in Individuals with Chronic Low Back Pain
Purpose: Neuroscience studies suggest that Chronic Low Back Pain (CLBP) is associated with central sensitization, and maladaptive reorganization of the brain; this introduced a new target for LBP treatment. Studies revealed that cortical and peripheral electrical stimulation can be beneficial in regulating brain neuronal activity. However, there is a scarcity of evidence to support the effects ...

Background: Motor function impairment occurs in approximately two-thirds of patients with subcortical stroke. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive technique for modulating cortical excitability. Objectives: The present study was designed for assessing the efficacy of high-frequency rTMS (5 Hz) on ipsilesional primary motor cortex in patients with subcortical stro...
