Research Methods : Behavior Studies

Research in our group is conducted using a variety of techniques and has included, for example, measuring and manipulating behavior in the lab, trapping animals in the field, immunohistochemistry, tract tracing, monitoring and manipulating patterns of gene expression, and implanting neural tissues from one species into the brains of another.rack

A rack of animals housed with running wheels. We also use motion detectors and implanted transmitters to monitor behavior.
