Here we measure synaptic density with positron emission tomography (PET) to investigate the learning-induced synaptic plasticity more directly, and MRI-based GMV to investigate structural plasticity.

Participants’ performance improved significantly, and more for the complex than the simple training group. The VOI-based PET and GM analyses did not yield any significant results. In this pilot study, we did not identify significant changes in synaptic density as a surrogate marker for plasticity after motor learning in the a priori chosen VOIs.
