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.
