Research Description:

Vertebrate locomotion is coordinated by neural circuits in the spinal cord called central pattern generators (CPGs). Spinal cord injury (SCI) can result in severe disruption of the spinal CPG, and repairing the spinal cord following SCI will require an understanding of the locomotor CPG. My work is focused on the role of a specific group of ventral neurons in the CPG by measuring their necessity locomotion, pattern of activity, and intrinsic membrane properties.
