A Method for Electrical Stimulus Artifact Removal Exploiting Neural Refractoriness: Validation by Contrasting Cathodic and Anodic Stimulation

Arie Nakhmani, J. Block, M. Awad, J. Olson, Rachel June Smith, J. Nicole Bentley, Marshall T. Holland, Sarah A. Brinkerhoff, Christopher L. Gonzalez, Michael A. Moffitt, Harrison C. Walker

This paper introduces a method to remove electrical stimulus artifacts by exploiting neural refractoriness, showing distinct neural responses to cathodic and anodic stimulation.

Differential Contribution of Sensorimotor Cortex and Subthalamic Nucleus to Unimanual and Bimanual Hand Movements

Christina M. Merrick, Owen Doyle, Natali E. Gallegos, Zachary T. Irwin, Joseph W. Olson, Christopher L. Gonzalez, Robert Thomas Knight, Richard B. Ivry, Harrison C. Walker

The paper investigates how sensorimotor cortex and subthalamic nucleus encode unimanual and bimanual hand movements, finding that STN encodes movements for both hands and is context-sensitive, while SMC is contralaterally biased and context-insensitive.
