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 ...

background and aim: tinnitus is an auditory phantom percept in the absence of any objective physical sound source. although advances have been made in its treatment, there is very low percent of patients that report an elimination of their tinnitus. a novel approach using noninv­asive neuromodulation has emerged as an inter­esting and promising modality for tinnitus relief. our aim in this revi...

Background: Pre-op anxiety has adverse effects on the patientchr('39')s anesthesia and treatment. Currently, electrical interventions are widely used as non-invasive methods to control pre-op anxiety and may have advantages as compared with medical therapies. This study aimed to determine the effect of transcranial alternating current stimulation on anxiety and hemodynamic response of patients ...

a b s t r a c tthe applications of neurophysiological therapy techniques range far and few in the realm of modern day medicine. however, the concept of electromagnetic stimulation, the basis for many noninvasive brain stimulation (nibs) techniques today, has been of interest to the scientific community since the late nineteenth century. recently, transcranial direct current stimulation (tdcs) a...

Transcranial alternating current stimulation (tACS) seems likely to open a new era of the field of noninvasive electrical stimulation of the human brain by directly interfering with cortical rhythms. It is expected to synchronize (by one single resonance frequency) or desynchronize (e.g., by the application of several frequencies) cortical oscillations. If applied long enough it may cause neuro...

Dozens of animal studies of transcranial direct current stimulation (tDCS) and transcranial alternating current stimulation (tACS) have provided insight into the cellular mechanism of stimulation. Biomarkers of tDCS/ tACS responses at the neurophysiological, behavioral, and molecular levels provide a basis to design clinical interventions that engage specifi c targets. This chapter provides a b...
