transcranial current stimulation (tcs) is a neuromodulation method in which the patient is exposed to a mild electric current (direct or alternating) at 1-2 ma, resulting in an increase or a decrease in the brain excitability. this modi.cation in neural activities can be used as a method for functional human brain mapping with causal inferences. this method might also facilitate the treatments ...

introduction: although hippocampus is the most famous brain area involved in temporal lobe epilepsy, hippocampal kindling (hk) develops very slowly. hence, rapid kindling is usually preferred to the traditional kindling and it is widely used. in this article we aimed at finding the optimal stimulus pattern, which yields the fastest hk rate. methods: stimulus patterns with different duration (2,...

introduction: opiates cause dependency via affect on central nervous system. locus coeruleus nucleus is a main group of noradrenergic neurons in the brain that plays an important role in the expression of opioid withdrawal signs. during opioid withdrawal, brain waves change in addition to physical and behavioral signs. in this study, we examined the effects of locus coeruleus electrical stimula...

Background: The interaction between antiepileptic drugs and brain electrical stimulation is a potential therapy to control of seizures in patient with pharmacoresistance to drugs. So, the aim of present study was designed to determine the effect of a sub effective dose of sodium valproate combined with low-frequency electrical stimulation during kindling. Material and Methods: One tripolar ele...

Background and purpose: Auditory-verbal memory decreases with age. One method to compensate this weakness is transcranial direct current stimulation. The current study investigated the effect of Anodal Transcranial Direct Current Stimulation on auditory-verbal memory performance of healthy elderly people. Materials and methods: In a randomized clinical trial, 42 healthy subjects with no histor...

Previous studies indicate that Matricaria chamomilla (MC), a folk remedy plant, is very useful in the treatment of spasmogenic bowel diseases but the way of its action is not clear. For this purpose, we studied the effect of MC extract on the electrically activation in Guinea-Pig ileum in an invitro model. We used guinea pig in this study. After of kill, we brouhght out a piece of ileum and fix...
