(a) MP-RAGE images of thalamocortical tract-tracing with the injection of MnO@SiO2 nanoparticles at the cortex (S1). The arrow in the left image indicates the enhanced thalamus compared to contra-lateral hemisphere. The arrow in the right image is the injection site. Both images were acquired 24 hours after injection was made at the cortex. (b) T2-weighted images of thalamocortical tract-tracing experiment with the injection of Fe3O4@SiO2 nanoparticles in the S1. The left image with an arrow is the thalamus showing no enhancement at 20 hours post injection. The right image is the injection site showing clear dark contrast. Both images were acquired 20 hours after injection was made at the cortex.
