Studies suggest that endogenous field effects may play a role in neuronal oscillations and communication. Non-invasive transcranial electrical stimulation with low-intensity currents can also have direct effects on the underlying cortex as well as distant network effects. While Parkinson's disease (PD) is amenable to invasive neuromodulation in the basal ganglia by deep brain stimulation (DBS),...

Introduction Human multimodal vestibular cortical regions are bilaterally anterior insulae and posterior opercula, where characteristic vestibular-related cortical potentials were previously reported under acoustic otolith stimulation. Galvanic vestibular stimulation likely influences semicircular canals preferentially. Galvanic stimulation was compared to previously established data under acou...

This study assessed the behavioral and dendritic structural effects of combining subdural motor cortical electrical stimulation with motor skills training following unilateral sensorimotor cortex lesions in adult male rats. Rats were pre-operatively trained on a skilled forelimb reaching task, the Montoya staircase test, and then received endothelin-1 induced ischemic lesions of the sensorimoto...

Abstract Stroke remains a leading cause of long-term disability in developed countries and the second death worldwide. Recent decades have witnessed substantial progress understanding pathophysiology ischemic stroke treatment stroke-related motor deficit. However, current therapies fail to offer patients satisfactory improvements. Therefore, more effective approach for treating deficit is still...

Abstract Oscillations play a pivotal role in shaping cerebellar local activity and its communication with neocortical areas involved learning motor skills. Previous studies have emphasized the presence potentially important of beta (15-30 Hz) oscillations such processes. Yet, distribution causal nature interregional synchronization patterns at frequencies remain elusive. The present study aims ...

Cortical representations of muscles can be probed non‑invasively using transcranial magnetic stimulation (TMS) motor mapping. TMS mapping applied both in research and clinical settings to assess cortex reorganization under the influence various factors, clarify pathophysiological mechanisms system damage diseases, develop novel biomarkers this damage. The article discusses main methodological a...

[Purpose] This study examined the effects of galvanic vestibular stimulation on motion-related cortical potential. [Subjects and Methods] Fourty healthy female adult subjects each received galvanic vestibular stimulation or sham treatment. For galvanic vestibular stimulation, the anode and cathode were applied to the right and left mastoid processes, respectively, for 10 minutes. Motion-related...

Abstract Introduction: Transcranial Direct Current Stimulation (TDCS) can modulate intrinsic cortical activity by stimulating specific brain areas. TDCS produces peripheral somatosensory co-stimulation that may contribute to the neuro-modulatory effects and hamper effective blinding. Objective: To assess how topical administration of numbing cream modifies subjective tingling experience during ...
