This study shows that individuals with tetraplegia exhibit finger-specific brain activity in ipsilateral S1 without peripheral input, challenging the idea that somatotopic activity depends on sensory reafference.

This study investigates face-to-hand area remapping in human cervical SCI patients and finds no significant evidence of such remapping in fMRI experiments.

This study shows that top-down processing can activate early somatosensory nuclei in humans with spinal cord injury, even when peripheral input is absent.

This study benchmarks four cervical spinal cord RF coils at 7 T MRI across multiple centers, identifying performance differences and proposing a standardized evaluation protocol.

This study uses 3T fMRI and multivariate analysis to distinguish functional activity of adjacent somatosensory nuclei in the brainstem, thalamus, and S1, showing improved decoding compared to univariate methods.

The paper introduces EPISeg, a deep learning model for automated spinal cord segmentation on gradient-echo EPI data, showing improved performance over existing methods.

This study shows body size parameters significantly correlate with brain and spinal cord MRI metrics and should be included in neuroimaging studies.

The paper shows that motor imagery and execution activate similar, stable finger representations in the sensorimotor cortex over time.

This study shows that TMS-based neurofeedback training improves neuroplastic changes in the sensorimotor cortex by enhancing finger-specific motor representations.

ACID is an open-source MATLAB toolbox for processing and modeling diffusion MRI data from brain, spinal cord, and ex vivo specimens, incorporating artifact correction, biophysical models, and BIDS compatibility.

This study demonstrates the feasibility of BOLD fMRI in detecting neuronal activation in the lumbosacral cord during lower extremity motor tasks and shows TE-dependent effects on BOLD signal.

This study uses a novel MRI-safe vibrotactile stimulation device to map somatotopy in the human primary somatosensory cortex for hand and face regions.

This study shows that somatosensory representations of paralyzed hands are preserved in SCI patients but deteriorate over time, suggesting potential for neuroprosthetic use despite sensory and motor loss.

This study shows that motor skill learning involves coherent waves of myelin plasticity in the corticospinal-hippocampal loop, with spatial and temporal patterns linked to training performance.
