The crossmodal congruency task as a measure of intuitiveness of sensory feedback in the lower limb

The study tests if a crossmodal congruency task can measure the intuitiveness of sensory feedback in lower limb prostheses, finding it effective at the knee but not the foot.

Selectivity of Lateral Epidural Spinal Cord Stimulation with Varying Electrode Diameters and Stimulation Configurations

This study evaluates how electrode size and stimulation configurations affect nerve selectivity in spinal cord stimulation, finding that 500 µm electrodes provide the best selectivity.

Cervical spinal cord stimulation disrupts proprioception yet improves voluntary arm reaching

This study shows that cervical spinal cord stimulation impairs proprioception but improves voluntary arm reaching in post-stroke patients.

Functional Somatotopy of Lumbar Dorsal Rootlets and its Role in Selective Recruitment via Lateral Spinal Cord Stimulation

This study shows that lateral spinal cord stimulation (LSCS) selectivity is limited by the coarse organization of lumbar dorsal rootlets, not electrode design, and suggests improving electrode placement may enhance percept localization.

SpIC3D imaging: Spinal In-situ Contrast 3D imaging

This paper introduces SpIC3D, a 3D imaging method for high-resolution visualization of spinal structures, enabling quantification of neuronal density and volumetric reconstruction for computational modeling.

Epidural Spinal Cord Recordings (ESRs): Sources of Artifact in Stimulation Evoked Compound Action Potentials

This study identifies and characterizes sources of artifact contaminating evoked compound action potentials (ECAPs) in epidural spinal cord recordings, highlighting challenges in distinguishing neural signals from artifacts in a swine model.

Anesthesia suppresses gastric myoelectric power in the ferret

This study shows that general anesthesia reduces gastric myoelectric power in ferrets and that behavioral movement increases signal power compared to rest.

Tuning electrical stimulation of the cervical vagus nerve for abdominal signaling while reducing cardiovascular side effects

This study demonstrates selective cervical vagus nerve stimulation using flexible cuff electrodes to target abdominal pathways while minimizing cardiovascular side effects in a rat model.

Functional and Structural Moment Arm Validation for Musculoskeletal Models: A Study of the Human Forearm and Hand

The paper validates and scales musculoskeletal models of the human forearm and hand using posture-dependent moment arms, isometric force measurements, and error detection to improve accuracy in torque prediction.

Heuristic Spike Sorting Tuner (HSST), a framework to determine optimal parameter selection for a generic spike sorting algorithm

HSST optimizes spike sorting parameters using neurophysiological metrics, improving sorting accuracy and robustness across varying conditions.

Machine learning prediction of emesis and gastrointestinal state in ferrets

This study uses machine learning to predict emesis and gastrointestinal states in ferrets using implanted myoelectric signals.
