Effect of vagotomy and muscular paralysis on the MEPdia induced by a single TMS pulse at −6 mm from Bregma.

<p>A) Representative MEPdia before vagotomy, after vagotomy and injection of a paralytic agent (gallamine trietiodide) obtained with the “Unshielded” coil. B) Representative MEPdia before vagotomy, after vagotomy and injection of a paralytic agent (gallamine trietiodide) obtained with the “Shielded” coil. Note that the vagotomy does not affect the MEPdia, and the paralytic agent abolish the MEPdia in both conditions in A and B. C) Histogram of the MEPdia amplitude before vagotomy, after vagotomy and following the injection of paralytic agent in the “Unshielded” (black histogram) and “Shielded” (White histogram) on the TMS coil. *: p<0.001.
