General information

The Wagenaar Lab is part of the Division of Biology and Biological Engineering at the California Institute of Technology. We study the neuronal basis of sensory processing and sensory-guided behavior, with a specific focus on crossmodal sensory integration in the leech and on functional and anatomical circuit mapping.
