All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The transcutaneous application of a sub-sensory electrical stimulation to the vestibular afferents, known as noisy galvanic vestibular stimulation (nGVS), is thought to cause a reduction in postural sway at optimal amplitude intensities due to a mechanism known as stochastic resonance (SR). SR is a phenomenon whereby the addition of low amplitude noise to a non-linear system can be beneficial rather than detrimental. In humans, behavioral markers of SR in postural sway have been inconsistent, potentially due to insufficient power or false positives. Therefore, the main purpose of this study was to determine whether the frequency of observing SR-like effects improves …
