Intracortical BCI Performance is Robust to Changes in Attentional Load During Dual-Tasking

This study examines how attentional load affects intracortical brain-computer interface (iBCI) performance during dual-tasking, finding robust performance but individual variability.

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.

Appellian Neural Networks

The paper introduces ANNet, a physics-informed neural network that unifies inverse and forward dynamics computations using a shared learned representation based on Appell's acceleration energy.

Early electrical stimulation promotes functional recovery after volumetric muscle loss

This study shows that early electrical stimulation improves functional recovery in rats with volumetric muscle loss by enhancing muscle remodeling.

Enabling Skilled Human-Computer Interaction After Paralysis via a Wearable sEMG Interface

People with tetraplegia used a wristband sensor to detect forearm motor unit firing and perform human-computer interaction tasks.

Dynamic, behavior-dependent interactions between dorsal striatal dopamine and glutamate release predict cognitive flexibility and punishment resistant cocaine use

The paper examines dopamine and glutamate dynamics in rat striatum during cognitive tasks, linking them to strategy switching and cocaine use patterns.

Changes in Gait Asymmetry May Be Caused by Adaptation of Spinal Reflexes

This study uses a neuromuscular model to show that spinal reflex gain adaptations, not belt speed changes, drive gait asymmetry during split-belt treadmill locomotion.

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.

High-Frequency Stimulation Does Not Improve Comfort of Transcutaneous Spinal Cord Stimulation

This study investigates whether high-frequency transcutaneous spinal cord stimulation (tSCS) is more comfortable than conventional tSCS at therapeutic amplitudes, finding no significant difference in discomfort ratings.

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.

Augmenting Quadriplegic Hand Function Using a Sensorimotor Demultiplexing Neural Interface

This study demonstrates that residual sensory signals from a paralyzed hand can be decoded from the motor cortex and used to enhance sensorimotor function via a closed-loop brain-computer interface.
