Locating the superior temporal gyrus

The different methods for finding the superior temporal gyrus and how to position the coil.

Stimulation of the superior posterior temporal gyrus can be used in auditory hallucinations or tinnitus, using a low-frequency inhibitory pulse at 1 Hertz. To locate it, you can do the same EEG measurements or you can basically locate the spot essentially over the preauricular point. The alternative is halfway between T3 and P3, which is about there (points at the superior temporal gyrus between T3 and P3).

So, what we do is, we line up the coil, there (handle pointing backward), and we stimulate that way. Sometimes, if that is uncomfortable, we stimulate it from the other side. Rarely is it necessary to come in from the top. All three are different stimulations, with different patterns of electrical and magnetic fields.
