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

This study investigates how rare rewards affect performance and neural activity in rhesus monkeys during a color change detection task, finding detrimental changes in V4 population activity linked to perceptual choking.

The paper identifies distinct neural modes in the sensorimotor cortex that encode grasp force and timing during isometric grasps in tetraplegic individuals.

The paper shows that posture and goal information in motor cortex are organized in separate, orthogonal subspaces, with posture information being stable across tasks.

This study investigates how reward influences movement vigor through multiple mechanisms in motor cortical areas by analyzing neural activity in rhesus monkeys.

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

The paper investigates how high rewards affect neural activity in Rhesus monkeys during a reaching task, finding that large rewards reduce neural information about movement plans.

This paper develops a theory explaining BCI learning through low-dimensional control strategies, validated with experimental data.

The paper shows that motor cortex maintains similar neural dynamics during motor execution and imagery by recreating missing components in a unique imagery subspace.

This study investigates how sensory context affects the ability of monkeys to volitionally modulate single neurons in the motor cortex during a cursor control task.

This study evaluates dimensionality reduction methods for calcium imaging data and introduces CILDS, which outperforms existing methods in recovering low-dimensional neural activity.

The paper investigates the effects of dark exposure on visual processing in adult mice, finding that while it temporarily reduces neural discriminability, it stabilizes orientation preference and improves discriminability for both low and high spatial frequency stimuli.

The paper shows that learning a new BCI map alters neural activity in a way that preserves performance on a familiar map, suggesting a mechanism for learning multiple motor behaviors without interference.

The paper shows that new skill learning in mice does not disrupt existing visual cortex function, but increases representational drift in some neurons.

The paper investigates how internal states like arousal affect neural engagement during learning in non-human primates using a BCI paradigm, finding that abrupt changes in engagement influence learning speed for different task goals.

This study shows that early postnatal visual experience enhances natural scene discriminability in V1 by reducing low-spatial frequency grating-responsive neurons and increasing natural scene responsiveness.
