Short-latency TMS-evoked potentials as a measure of interhemispheric conduction delay
Measuring conduction delay of cortico-cortical connections is still a major challenge that limits a thorough understanding of neural communication. For example, it has been theorized that transcallosal conduction delay (TCD) is a crucial feature of long-range connectivity influencing hemispheric dominance and behavioral performance, but more empirical evidence is needed. Here, we propose the use of TMS-evoked potentials (TEPs) to obtain temporally precise cortical measures of TCD. We report evidence in the motor system that applying TMS on target areas induces secondary responses in contralateral regions and that these responses, that can be measured from TEPs, depend on the microstructural integrity of the corpus callosum from DTI. Importantly, TEPs provide separate measures of TCD in each direction of the corpus callosum, revealing the importance of asymmetric conduction delay for bimanual coordination.
