This study was designed to determine whether a silent period could be elicited in the diaphragm electromyographic (EMG) activity by transcranial magnetic stimulation (TMS) of the motor cortex and, if so, to assess the influence of reflex or voluntary control of breathing on diaphragmatic cortical silent period (cSP). Diaphragmatic EMG activity was recorded in six healthy volunteers after motor cortex TMS triggered by the inspiratory flow peak and applied during forced inspiration (FI), voluntary hyperventilation (vHV) and reflex hyperventilation (rHV) to a CO(2) stimulus. Electrophysiological and respiratory parameters were studied, including diaphragmatic cSP duration and transdiaphragmatic pressure swing (DeltaPdi). A diaphragmatic cSP was found and correlated with DeltaPdi values. DeltaPdi and cSP duration were similar in the vHV and rHV conditions but were significantly increased during FI. This study established for the first time the existence of a diaphragmatic cSP to motor cortex TMS. The diaphragmatic cSP duration depended on the magnitude of the respiratory effort, as assessed by DeltaPdi, but not on the mechanism (volitional or reflex) of diaphragm activation.
