cSP Experiment: Effect of Motor Task on cSP Duration

In this video, we show a brief overview of an experiment aiming to test the effect of motor task (i.e., index finger abduction, pincer grip, and power grip) on cortical silent period (cSP) duration. This experiment was adapted from a previous study by Tinnazi and colleagues in 2006:
Tinazzi, M., Farina, S., Tamburin, S., Facchini, S., Fiaschi, A., Restivo, D., & Berardelli, A. (2003). Task-dependent modulation of excitatory and inhibitory functions within the human primary motor cortex. Experimental brain research, 150(2), 222-229.
In the video, we also refer to our recent paper, Hupfeld et al. 2020 in the Journal of Neuroscience Methods, which discusses methodological considerations for designing cSP experiments and the effects of different post-processing choices:
