Decoupling simultaneous motor imagination and execution via orthogonal ECoG neural representations

This study decodes simultaneous motor execution and imagination using ECoG signals by identifying orthogonal neural subspaces.

Evidence for common spike-based temporal coding of overt and covert speech in pars triangularis of human Broca's area

The paper shows that speech is encoded in Broca's area through both spike rates and precise spike timing, with temporal coding being more conserved between overt and covert speech.

Behavioral changes preceded by subthalamic nucleus alterations in a progressive macaque model of Parkinson's disease.

This study shows that STN dysfunction precedes motor symptoms in a macaque PD model and suggests targeted stimulation strategies for both motor and non-motor symptoms.

Too much or not enough? Optimal level of human intracranial theta activity for rule-switching in the subthalamo-medio-prefrontal circuit

This study investigates the optimal level of theta activity in the subthalamo-medio-prefrontal circuit for rule-switching, finding a Goldilocks effect where moderate theta power supports successful switching while excessive or delayed theta leads to errors.

The role of the thalamus in human reinforcement learning

This study investigates the role of the thalamus in human reinforcement learning using intra-thalamic electrophysiological recordings and identifies temporally structured oscillations as encoding key learning signals.

Toward a unified connectomic target for deep brain stimulation in obsessive-compulsive disorder

The paper identifies a common neural tract associated with treatment response in OCD patients undergoing DBS targeting different brain regions.

Acoustic contamination of electrophysiological brain signals during speech production and sound perception

This study identifies acoustic contamination in neural recordings during speech and sound processing, showing it can artificially improve speech decoding performance.
