Figure 9 Time series of a voxel in primary motor cortexshowing activation in response to finger taps; the
subject is tapping her fingers for ten trials then keeping them still for ten trials. The TMS is triggered in
every trial that she taps her fingers. The vertical lines separate each block of twenty trials.

voxel whose time series is shown in figure 9.
Further Refinement, the TMS Coil Acting as an Antenna and Noisefrom the TMS Console
Although the majority of noise has been removed, a small amount remains due
to the now open TMS coil acting as an antenna. Any noise picked by the leads of the coil
