Transcranial alternating current stimulation (tACS) and transcranial random noise stimulation (tRNS) have been shown to have physiological and functional effects on brain excitability and motor behavior. Yet, little is known about their effects in the swallowing system. To examine the effects and optimal stimulation parameters of tACS and tRNS for modulating excitability of human pharyngeal motor cortex. 10Hz (alpha), 20Hz (beta), 70Hz (gamma) tACS, 0.1-640Hz (full-spectrum) tRNS, and sham were applied over pharyngeal motor cortices a
