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 of many neuropsychiatric disorders based on its inexpensive, simple, safe, noninvasive, painless, semi-focal excitatory and inhibitory effects. Given this, a comparison amongst different brain stimulation modalities has been made to determine the potential advantages of the TCS method. In addition, considerable methodological details on using TCS in basic and clinical neuroscience studies in human subjects have been introduced.

Neuroimaging studies have shown that one of the most important areas corresponding to the working memory is the dorsolateral prefrontal cortex (DLFPC). This study was aimed to assess whether bilateral modulation of the DLPFC using a noninvasive brain stimulation, namely transcranial direct current stimulation (tDCS), modi.es the working memory function in healthy adults.Methods: In a randomized sham-controlled cross-over study, 60 subjects (30 Males) received sham and active tDCS in two subgroups (anode left/cathode right and anode right/cathode left) of the DLPFC. Subjects were presented working memory n-back task while the reaction time and accuracy were recorded.Results: A repeated measures, mixed design ANOVA indicated a signi.cant difference between the type of stimulation (sham vs. active) in anodal stimulation of the left DLPFC with cathodal stimulation of the right DLPFC [F(1,55)= 5.29,  P=0.019], but not the inverse polarity worsened accuracy in the 2-back working memory task. There were also no statistically signi.cant changes in speed of working memory [F(1,55)= 0.458 ,P=0.502] related to type or order of stimulation..Discussion: The results would imply to a polarity dependence of bilateral tDCS of working memory. Left anodal/ right cathodal stimulation of DLPFC could impair working memory, while the reverser stimulation had no effect. Meaning that bilateral stimulation of DLFC would not be a useful procedure to improve working memory.

The proposed method is based on fuzzy logic control. Fuzzy logic control is a methodology of intelligent control that mimics human decision-making process. This type of control method can be very useful for the complex uncertain systems that their mathematical model is unknown. To increase the stability and speed of the system’s response and reduce the steady-state error, we combine the FLC with a lead (lag) compensator. The experiments are conducted on .ve rats. Microelectrodes are implanted into the spinal cord to provide selective stimulation of plantar.exor and dorsi.exor. The results show that motor functions can be restored using ISMS.

The data collected from47 idiopathic and 52 non-idiopathic SNHL cases. AECAs were measured by indirect immuno .uorescence assay and compared in sera and perilymphatic .uids between the two groups. P-value<0.05 was considered signi.cant.Results: Idiopathic SNHL was diagnosed in 47.5% of cases. Positive AECA results in serum and perilymphatic .uid were 10% and 12%, respectively. Although AECA results in perilymphatic .uids were different between idiopathic and non-Idiopathic SNHL patients (PV<0.05), AECAs in serum showed no signi.cant difference between the two (PV=0.1).No signi.cant difference was detected between the mean age of idiopathic and non-idiopathic SNHL patients with positive AECAs in serum and perilymphatic .uids (PV=0.2 PV=0.2).Discussion: Idiopathic SNHL was diagnosed in 47.5 % of studied cases. Idiopathic SNHL has a poor out come in children. In cases with idiopathic SNHL, .nding AECAs in perilymphatic .uids are more valuable than in the serum. We suggest that serum and perilymphatic .uids testing for AECAs would be helpful in management of idiopathic SNHL cases. Speci.c immunosuppressive treatments for selected cases suffering from Idiopathic SNHL (only in those older than 5) might be successful in disease management.

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 a chronic manner (one stimulation per 24 h). In other experimental groups, animals received low-frequency stimulation (8 packages at 100 s intervals, each package contained 200 monophasic square-wave pulses, 0.1 ms pulse duration at 1 Hz andAD threshold intensity) in amygdala, piriform cortex or substantia nigra 60 seconds after the kindling stimulation, the AD duration and daily seizure stages were recorded. The obtained results showed that administration of LFS in all three regions reduced electrical and behavioral parameters of the kindling procedure. However LFS has a stronger inhibitory effect on kindling development when applied in substantia nigra compared to the amygdala and piriform cortex which reinforce the view that the substantia nigra mediates a crucial role in amygdala-kindled seizures. LFS had also greater inhibitory effects when applied to the amygdala compared to piriform cortex. Thus, it may be suggested that antiepileptogenic effect of LFS depends on its target site and different brain areas exert different inhibitory effects on kindling acquisition according to the seizure focus.}, Keywords = {Low-Frequency Stimulation, Epilepsy, Kindling,Amygdala,Piriform Cortex, Substantia Nigra.}, volume = {4}, Number = {3}, pages = {250-256}, publisher = {Iran University of Medical Sciences}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, url = {http://bcn.iums.ac.ir/article-1-409-en.html}, eprint = {http://bcn.iums.ac.ir/article-1-409-en.pdf}, journal = {Basic and Clinical Neuroscience}, issn = {2008-126X}, eissn = {2228-7442}, year = {2013} } @article{ author = {Jaberzadeh, Shapour and Zoghi, Maryam}, title = {Non-Invasive Brain Stimulation for Enhancement of Corticospinal Excitability and Motor Performance}, abstract ={During the past .. years, non-invasive .rain stimulation has .ecome an emerging .eld in clinical neuroscience due to its capability to transiently modulate corticospinal excitability, motor and cognitive functions. .hereas transcranial magnetic stimulation has .een used e.tensively since more than t.o decades ago as a potential .neuromodulator., transcranial current stimulation .tCS. has more recently gathered increased scienti.c interests.
