High-frequency test stimulation for tremor suppression is a standard procedure for functional target localization during deep brain stimulation. This method does not work in cases where tremor vanishes intraoperatively, for example, due to general anaesthesia or due to an insertional effect. To overcome this difficulty, we developed a stimulation technique that effectively evokes tremor in a we...

The effects of chronic morphine administration on the development of long-term potentiation (LTP) were investigated at the Schaffer collateral-CA1 pyramidal cell synapses of the rat hippocampal slices using primed-bursts tetanic stimulation. Significant enhancement of orthodromic population spike (OPS) was found for all stimulus intensities after tetanic stimulation. OPS enhancement was greates...

Low frequency stimulation (LFS) is a potential alternative therapy for epilepsy. However, it seems that the anticonvulsant effects of LFS depend on its target sites in the brain. Thus, the present study was designed to compare the anticonvulsant effects of LFS administered to amygdala, piriform cortex and substantia nigra on amygdala kindling acquisition. In control group, rats were kindled in ...

objectives: low birth weight neonates need complementary interventions (e.g. tactile kinesthetic stimulation) to promote their development. this study was conducted to determine the effect of tactile- kinesthetic stimulation (tks) on motor development of low birth weight neonates. methods: in this clinical trial study, sample was made out of 40 inborn lbw neonates who were divided into two grou...

background and aim: the normal response of h-reflex depression (hd) was reduced in chronic spinal cord injury (sci) patients. the reduction of this normal response can lead to increase the muscle tone and spasticity. the purpose of this study is to investigate the effect of tripolar cathodal stimulation on hd in sci patients.   materials and methods: this study was conducted in 10 volunteered s...
