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 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 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.

This study shows that human participants can voluntarily control their arousal state using pupil-based biofeedback, which modulates brainstem activity and physiological responses.

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 examines cortical hand map changes after finger nerve block, finding persistent representation despite input loss, suggesting distributed processing and homeostatic mechanisms.

The paper shows that vibrotactile working memory modulates somatotopic finger representations in primary somatosensory cortex during the delay period without tactile stimulation.

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 TMS-based neurofeedback training enables participants to selectively modulate corticomotor excitability of individual fingers during mental imagery without physical movement.

The paper investigates finger representation in the primary somatosensory cortex of congenitally blind individuals using fMRI and psychophysics, finding no increased hand representation but activation of the middle temporal complex during finger movement.
