These researchers set out to determine the best parameters for TaVNS. The found 500μ and 25Hz or 10Hz were most effective. They used the tragus for stimulation. Tragus may not be the most effective, but it does have some effect on the auricular branch of the vagus nerve. The authors do not specify which ear they used.
I use 500μ and 25 hz intermittent to mitigate the tolerance effect of continuous stimulation. I sometimes use alternating Left and Right stimulation or Left alone. (It makes me wonder if I should try the right ear more often to see…)
