About Dr. Comer's Research

Research in my laboratory is in the area of sensorimotor integration, and we take a comparative and evolutionary approach to this important problem. We are specifically interested in how visual and touch-sensory systems encode information about the location of stimuli in the environment, and how that information is translated into commands for appropriately directed movements. This sort of translation is performed rapidly and efficiently by a nervous system every time an animal or a person turns to locate a sound, flicks their eyes to focus on something interesting, or turns away to evade something threatening. It is not known at present exactly how these translations are made, and my lab is trying to analyze how they happen at a detailed cellular level.

We have been analyzing the neural circuits underlying several specific spatially directed behaviors: A variety of techniques are used in our experiments - cellular electrophysiology, single cell enzymatic lesions, quantitative behavioral analyses and computer-based simulations to name a few. Projects include: 1) Mechanosensory and visual guidance of behavior in insects, 2) touch-sensory guidance of vertebrate orienting behavior in rodents (mole-rats), 3) "neuroinformatics" - the use of database resources to advance neurobiological research.
