This study aims at understanding the perceptual effect of combined stimulations of a human optic nerve. Phosphenes were obtained by electrical stimulations through a 4-contact spiral cuff electrode previously implanted around the right optic nerve of a completely blind retinitis pigmentosa patient. Simultaneous, interlaced or sequential stimulations resulted in the perception of multiple phosph...

Background: Lumbosacral orthosis (LSO) is commonly used for the treatment of back pain. The clinical andmechanical effectiveness of this device has been repeatedly investigated in several studies; however, its sensorimotoreffectiveness has been rarely considered. Regarding this, the aim of the current study was to investigate the effect ofa non-extensible LSO on postural stabi...

Radical surgical removal of WHO grade II glioma, when possible, appears currently the first treatment to delay the risk of anaplastic transformation. The goal of surgery is to maximize the quality of resection, while minimizing the risk of permanent neurological deficit. Thus, due to the frequent location of these lesions in eloquent areas, and because of an important interindividual anatomofun...

introduction: previous studies have been shown that low frequency stimulation (lfs) has an inhibitory effect on kindling acquisition. however, the mechanism of this effect has not been completely determined. in the present study, the effect of lfs of the perforant path on seizures induced by rapid perforant path kindling was investigated. methods: animals were kindled by electrical stimulation ...

For the recording of gustatory evoked responses, the tip of a stimulator is pressed vertically on one side of the tongue until the trigger pulses are generated by a switch attached to the bottom of the stimulator. According to our results, no detectable response was observed in the absence of taste. The positive waves were distinguishable by using the technique of superimposition before averagi...

objective: the aim of this study was to assess and compare the effect of two neurofeedback protocols (smr/theta and beta/theta) on adhd symptoms, selective attention and eeg (electroencephalogram) parameters in children with adhd. method: the sample consisted of 16 children (9-15 year old: 13 boys; 3 girls) with adhd-combined type (adhd-c). all of children used methylphenidate (mph) during the ...
