Several mechanisms have been proposed that control the amount of plasticity in neuronal circuits and guarantee dynamic stability of neuronal networks. Homeostatic plasticity suggests that the ease with which a synaptic connection is facilitated/suppressed depends on the previous amount of network activity. We describe how such homeostatic-like interactions depend on the time interval between tw...

Transcranial direct current stimulation (tDCS) is a non-invasive method of brain stimulation that has been intensively investigated in clinical and cognitive neuroscience. Although the general impression is that tDCS is a safe technique with mild and transient adverse effects (AEs), human data on safety and tolerability are largely provided from single-session studies in healthy volunteers. In ...

Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique that alters cortical excitability. Interestingly, in recent animal studies facilitatory effects of tDCS have also been observed on subcortical structures. Here, we sought to provide evidence for the potential of tDCS to facilitate subcortical structures in humans as well. Subjects received anodal-tDCS an...

BACKGROUND Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulatory technique and has previously been shown to enhance submaximal exercise by reducing rating of perceived exertion (RPE). The present study examined the effects of tDCS on high-intensity self-paced exercise in temperate conditions and fixed followed by maximal exercise in the heat; it was hypothesised that ...

از جمله تکنیک های شناخت عملکرد مغز می توان به تکنیک تحریک الکتریکی و مغناطیسی مغز اشاره نمود که در این پژوهش از تحریک الکتریکی مستقیم قشر مغز (tdcs) جهت بررسی ادراک زمان استفاده شده است. مطالعات متعدد تصویربرداری مغزی و مطالعات آسیبی نقشی را برای قشر آهیانه ای در تکالیف زمانی مختلف پیشنهاد کرده اند. همچنین مطالعات متعددی نیز نقش قشر آهیانه ای را در توجه مستمر، که نقش تعیین کننده ای در پردازش ها...

BACKGROUND Mal de debarquement syndrome is a medically refractory disorder characterized by chronic rocking dizziness that occurs after exposure to passive motion. Repetitive transcranial magnetic stimulation (rTMS) can acutely suppress the rocking dizziness but treatment options that extend the benefit of rTMS are needed. OBJECTIVES 1) To determine whether transcranial direct current stimula...

Despite the attention garnered by the home (or Bdo-it-yourself^) use of tDCS (transcranial direct current stimulation), little is known about the population of actual users. The present study aimed to provide a comprehensive examination of those who purchase tDCS devices: who they are, how they learn about tDCS, and why and how they stimulate. A link to an online survey was sent to those who ha...

We investigated whether stimulating the cerebellum and primary motor cortex (M1) using transcranial direct current stimulation (tDCS) could affect postural control in young and older adults. tDCS was employed using a double-blind, sham-controlled design, in which young (aged 18-35) and older adults (aged 65+) were assessed over three sessions, one for each stimulatory condition-M1, cerebellar a...

A commonly referenced transcranial Direct Current Stimulation (tDCS) safety threshold derives from tDCS lesion studies in the rat and relies on electrode current density (and related electrode charge density) to support clinical guidelines. Concerns about the role of polarity (e.g. anodal tDCS), sub-lesion threshold injury (e.g. neuroinflammatory processes), and role of electrode montage across...

Transcranial direct current stimulation (tDCS) is a useful noninvasive technique of cortical brain stimulation for the treatment of neurological disorders. Clinical research has demonstrated tDCS with anodal stimulation of primary motor cortex (M1) in Parkinson's disease (PD) patients significantly improved their motor function. However, few studies have been focused on the optimization of para...
