Transcranial direct current stimulation (tDCS) is a non-invasive method to modulate cortical excitability in humans. Here, we examined the effects of anodal tDCS on suprahyoid motor evoked potentials (MEP) when applied over the hemisphere with stronger and weaker suprahyoid/submental projections, respectively, while study participants performed a swallowing task. Thirty healthy volunteers were ...

Perceiving human motion, recognizing actions, and interpreting emotional body language are tasks we perform daily and which are supported by a network of brain areas including the human posterior superior temporal sulcus (pSTS). Here, we applied transcranial direct current stimulation (tDCS) with anodal (excitatory) or cathodal (inhibitory) electrodes mounted over right pSTS (target) and orbito...

Abstract Background Impaired movement preparation of both anticipatory postural adjustments and goal directed as shown by a marked reduction in the incidence StartReact responses during standing reaching task was reported individuals with stroke. We tested how transcranial direct current stimulation (tDCS) applied over region premotor areas (PMAs) primary motor area (M1) affect planning Methods...

PURPOSE Weak direct currents induce lasting alterations of cortical excitability in animals and humans, which are controlled by polarity, duration of stimulation, and current strength applied. To evaluate its anticonvulsant potential, transcranial direct current stimulation (tDCS) was tested in a modified cortical ramp-stimulation model of focal epilepsy. METHODS The threshold for localized s...

OBJECTIVE Invasive stimulation of the motor cortex has been used for years to alleviate chronic intractable pain in humans. In our study, we have investigated the effect of transcranial direct current stimulation (tDCS), a noninvasive stimulation method, for manipulating the excitability of cortical motor areas on laser evoked potentials (LEP) and acute pain perception. DESIGNS AND SETTINGS: Th...

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...

The effects of excitatory amino acid (EAA) receptor antagonists in blocking the synaptic transmission between gustatory fibers of the chorda tympani (CT) nerve and taste-responsive neurons within the nucleus of the solitary tract (NST) were examined electrophysiologically in urethan-anesthetized hamsters. Single neurons in the NST were recorded extracellularly and drugs were microinjected into ...

OBJECTIVE Pain remains a critical medical challenge. Current treatments target nociception without addressing affective symptoms. Medically intractable pain is sometimes treated with cingulotomy or deep brain stimulation to increase tolerance of pain-related distress. Transcranial direct current stimulation (tDCS) may noninvasively modulate cortical areas related to sensation and pain represent...

Abstract Egocentric representations allow us to describe the external world as experienced from an individual’s bodily location. We recently developed a novel method of quantifying weight given different body parts in egocentric judgments (the Misalignment Paradigm ). found that both head and torso contribute simple alter-egocentric spatial judgments. hypothesised artificial stimulation vestibu...

Acquisition of fine motor skills is a time-consuming process as it based on learning via frequent repetitions. Transcranial electrical stimulation (tES) promising means enhancing simple skill development neuromodulatory mechanisms. Here, we report that non-invasive neurostimulation facilitates the complex bimanual associated with surgical task. During training 12 medical students Fundamentals L...
