Bruce Carlson is a Professor of Biology at Washington University, specializing in neuroethology and evolutionary neuroscience. His laboratory focuses on the neurobiological basis of sensory information processing, animal communication, and the evolution of brain and behavior. Using weakly electric fish as a model system, his research explores how nervous systems integrate sensory input to guide behavior and how evolutionary pressures shape sensory systems and brain structures. Recent work includes a $980,000 NSF grant investigating neuroplasticity's role in behavioral evolution. The Carlson Lab employs electrophysiology, neuroanatomy, computational modeling, and behavioral analysis to study electrosensory systems. They emphasize the interplay between ecological context and evolutionary forces, particularly in mormyrid fish. Outreach initiatives include partnerships with Harris-Stowe State University to engage underrepresented students in research. Key research themes include the evolutionary drivers of sensory circuit changes, the link between brain size and energetic costs (e.g., reduced hypoxia tolerance in encephalized species), and the role of early-life experiences in shaping long-term behavioral outcomes. Publications span topics like synaptic plasticity, neural coding of communication signals, and comparative brain evolution in teleost fishes. Scientific awards include significant NSF funding, and his work has been highlighted in outlets like Science , Proceedings of the Royal Society B , and Neuroscience News . The lab also contributes to public education, using electric fish to illustrate neuroplasticity and growth mindset principles for K-12 students.
