Real-time intracortical decoding from human motor cortex reveals a task-independent commitment to act that aligns with conscious intent

This study decodes motor cortex activity in real-time to predict movement onset before action, showing a task-independent commitment to act that aligns with conscious intent.

Spatiotemporal encoding of touch signals in the human somatosensory and motor cortices

This study maps neural responses to touch in human somatosensory and motor cortices, revealing somatotopic activation in motor cortex during passive touch and limited vicarious encoding during observation.

A framework for quantifying the mechanics of dexterous grasp

The paper develops a framework to quantify the mechanics of primate dexterous grasp by measuring contact forces, kinematics, and joint torques using an experimental apparatus and musculoskeletal modeling.

A Generalist Intracortical Motor Decoder

The paper trains an autoregressive Transformer on neural spiking data to decode motor behavior, showing broad utility across tasks but highlighting limitations in scaling.

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.

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.

The integration of tactile and proprioceptive signals to achieve haptic object perception

The paper investigates how humans integrate tactile and proprioceptive signals for haptic object perception, finding that global shape and local features are encoded separately but integrated.

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.

Tactile localization of the breast, areola, and nipple

This study investigates tactile localization on the breast, areola, and nipple, finding lower precision compared to the hand and back, and highlighting distinct tactile properties of the nipple.

Texture coding in higher order somatosensory cortices of primates

The paper investigates texture coding in higher order somatosensory cortices of macaques, finding that S2/PV neurons represent texture more sparsely and encode task-related information rather than the stimulus itself.

Sensory computations in the cuneate nucleus of macaques

The paper investigates tactile signal processing in the cuneate nucleus of macaques and finds that CN neurons exhibit response properties more similar to cortical neurons than to their peripheral inputs.

THE EFFECT OF SCANNING SPEED ON TEXTURE-ELICITED VIBRATIONS

This study examines how scanning speed affects texture-elicited vibrations on human fingertips, finding increased intensity and frequency shifts with higher speeds.
