چکیده

We investigated the effect of repetitive transcranial magnetic stimulation (rTMS) on long-term potentiation (LTP) in the rat hippocampus. Rats were magnetically stimulated at a rate of 1000 pulses/day for 7 days by a round coil, in which the peak magnetic fields at the center of the coil were 0.75 and 1.00 T. LTP enhancement was observed only in the 0.75-T rTMS group, while no change was observed in the 1.00-T rTMS group. These results suggest that the effect of rTMS on LTP depends on the stimulus intensity.

The Neuroprotective Effects of Long-Term Repetitive Transcranial Magnetic Stimulation on the Cortical Spreading Depression-induced Damages in Rat’s Brain

Introduction: Cortical Spreading Depression (CSD) is a propagating wave of neural and glial cell depolarization with important role in several clinical disorders. Repetitive Transcranial Magnetic Stimulation (rTMS) is a potential tool with preventive treatment effects in psychiatric and neuronal disorders. In this paper, we study the effects of rTMS on CSD by using behavioral and histological a...

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...

The Effect of Noise Pollution Exposure during Pregnancy on Long Term Potentiation Induction in Pyramidal Neurons of Hippocampus CA1 area in Male Rat Offsprings

Background: It is believed that cognitive processing is easily disturbed by incompatible environmental stimulations. Many studies have shown that prenatal stress affects fetal brain development. The aim of this study was to evaluate the effect of noise pollution exposure during conception period on neural activity of hippocampus CA1 area in male rat offspring. Methods: Four groups of rats inclu...

Acquisition of ischemic tolerance by repetitive transcranial magnetic stimulation in the rat hippocampus.

We investigated the acquisition of ischemic tolerance in the rat hippocampus using repetitive transcranial magnetic stimulation (rTMS). Rats received 1000 pulses/day for 7 days, and the field excitatory postsynaptic potentials were measured in the hippocampal CA1. After slices were exposed to ischemic conditions, long-term potentiation (LTP) was induced. The LTP of the stimulated group was enha...

Role of adenosine receptors and protein phosphatases in the reversal of pentylenetetrazol-induced potentiation phenomenon by theta pulse stimulation in the CA1 region of rat hippocampal slices

The effect of theta pulse stimulation (TPS) on pentylenetetrazol (PTZ)-induced long-term potentiation of population spikes (PS) was studied in the hippocampal CA1 in vitro. A transient PTZ application produced a long-lasting enhancement of PS amplitude. A 3-min episode of TPS delivered at a higher intensity produced complete reversal of the PTZ potentiation when delivered during the last minute...
