Overlap in neural representations of coordinated wrist and finger movements in human motor cortex

The paper investigates how motor cortex encodes wrist and finger movements, finding shared neural signals for flexion-extension across digits and wrist, and demonstrating improved BCI control by accounting for these constraints.

Closed-loop error damping in human BCI using pre-error motor cortex activity

This paper introduces error modulation in motor BCIs using pre-error motor cortex activity to improve cursor control performance during online BCI tasks.

How different immersive environments affect intracortical brain computer interfaces

This study examines how immersive environments affect BCI performance, finding that prior experience with an environment is more important than its immersiveness for decoder performance and generalization.

Biomimetic multi-channel microstimulation of somatosensory cortex conveys high resolution force feedback for bionic hands

This study evaluates biomimetic multi-channel microstimulation for restoring high-resolution force feedback in bionic hands through somatosensory cortex stimulation.

A mosaic of whole-body representations in human motor cortex

The paper maps human motor cortex using microelectrode recordings, finding whole-body representations and challenging the traditional motor homunculus model.

Neuronal firing rate diversity lowers the dimension of population covariability

The paper shows that diverse neuronal firing rates reduce the dimensionality of trial-to-trial covariability in population responses across multiple species.

Microstimulation of human somatosensory cortex evokes task-dependent, spatially patterned responses in motor cortex

This study investigates how microstimulation of somatosensory cortex affects motor cortex activity in paralyzed individuals, finding task-dependent spatial patterns and showing that biomimetic stimulation improves control of a virtual hand.

Tessellation Of Artificial Touch Via Microstimulation Of Human Somatosensory Cortex

The paper investigates the localization of intracortical microstimulation-evoked sensations in human somatosensory cortex and demonstrates improved localization with multi-channel stimulation in a bionic hand.
