Observation-Related Activity in Human Motor Cortex Increases with Effector Anthropomorphicity

The paper investigates how motor cortex activity changes during observation of different anthropomorphic effectors, finding increased neural modulation with greater human-likeness of the observed agents.

Gesture encoding in human left precentral gyrus neuronal ensembles

This study analyzes neural activity in the precentral gyrus of two spinal cord injury patients to classify hand gestures with 70% accuracy, showing potential for intracortical BCI applications.

Pseudo-linear Summation explains Neural Geometry of Multi-finger Movements in Human Premotor Cortex

The paper shows that neural activity in human premotor cortex combines finger movements through pseudo-linear summation, with deviations that improve decoding performance.

Measuring instability in chronic human intracortical neural recordings towards stable, long-term brain-computer interfaces

The paper measures neural signal instability in long-term intracortical recordings to improve brain-computer interface performance through recalibration timing.

Mapping the computational similarity of individual neurons within large-scale ensemble recordings using the SIMNETS analysis framework

The paper introduces SIMNETS, a framework to map computational similarity of neurons in large-scale recordings, identifying subnetworks and validating cluster significance.

The neural representation of force across grasp types in motor cortex of humans with tetraplegia

This study examines how force and grasp are represented in motor cortex of tetraplegic individuals, finding that grasp affects force decoding and that grasp is more accurately classified than force.
