Figure 1. Experimental set‐up (A) and schematic illustration (B) of the eyeblink paradigm for cerebellar activity measurement.

Figure 1

The participant is seated inside a magnetically shielded room (MSR) wearing a customized scanner‐cast. Air‐puffs are delivered to the outer canthus of the participant's left eye via a nozzle. OPM sensors are inserted into slots covering the cerebellum and right somatosensory cortex. Two more sensors are placed in bilateral infra‐orbital slots to measure eyeblinks. Field‐nulling coils standing either side of the participant carry currents set so as to minimize the residual magnetic field in the MSR, which is measured by 4 reference OPMs prior to scanning. The task‐controlling laptop, located outside the MSR, sends synchronizing triggers that are recorded by the data acquisition PC during scanning. [Color figure can be viewed at wileyonlinelibrary.com]
