Welcome to the Neurorobotics Laboratory –Karen Moxon, P.I.

The primary focus of research in our lab is to understand how the brain encodes sensory information and integrates this to produce intelligent motor output. We want to be able to use this knowledge to investigate changes in network activity under conditions of neural injury or dysfunction.

Areas of research focus on Neural encoding and Brain Machine Interfaces with applications in Spinal Cord Injury and Epilepsy.

July 1st 2016: The Moxon lab is awarded a $3.8M grant from the National Institute of Health (R01 NS09697) entitled ‘Enchancing supraspinal plasticity to improve functional recovery after SCI’ The goal of this project is to understand the relationship between supraspinal plasticity and recovery of function after severe spinal cord injury. This project will study the anatomical, physiological and molecular changes in rats after SCI and therapy that are necessary to optimize recovery.

February 2015: Professor Moxon is elected a Fellow of the American Institute for Medical and Biological Engineers
