Laboratory of Neural Circuit Function

Animals sense their environmental signals and respond properly to survive and reproduce. Such sensory behaviors are regulated by the animal’s nervous system. The nervous system of an animal is composed as a network of many neurons, and the complex structure of the network is linked to its function. However, the specific relationships between the structure and function of nervous system remain largely unclear. Our research is directed toward further elucidating how environmental signals are received, integrated, and assessed by animals for proper sensory behaviors in their neuronal networks.

Specifically, our research focuses on the function of the nervous system of a model animal, the nematode Caenorhabditis elegans. There are a number of advantages to using the C. elegans nervous system for functional analyses, including the small size of the entire nervous system of the organism (only 302 neurons), the description of all neuronal connections, and its various types of behavioral plasticity. In addition, many sophisticated genetic and optical techniques are available to analyze and manipulate the animals' neural functions.
