Magnetic Resonance Imaging (MRI) Data Acquisition

Neuroimaging was performed on 44 participants. A subset of 20 participants (11 for HABIT, 9 for CIMT) repeated the neuroimaging immediately after the treatment (POST). Diffusion tensor imaging (DTI) was used to reconstruct the interhemispheric connections. MRI protocol was performed on a 3T Scanner (Siemens Magnetom Trio, Citigroup Biomedical Imaging Center, Weill Cornell Medical College). A total of 75 slices were acquired (matrix 112 × 112; Field of view = 224 mm; 65 directions; b value = 800 s/mm²; TR = 9000 ms; TE = 83 ms). The participants were positioned in a supine position with padding around the head to minimize movement and reduce noise. They were not physically constrained, nor did they receive any sedation.
