Research: Learning and Memory in Social Insects

The ability to form robust, long-term memories about their environment is a distinctive trait of social insects. My lab studies visual and olfactory, associative and non-associative learning in ants. Associative learning in insects is typically driven by repeated and spaced training, is long-term, depends on protein synthesis and is facilitated by different molecules and cells than non-associaitve learning. Non-associative learning in contrast, is driven more typically by serial training, is short-mid term and occurs independently of protein sythesis. We are currently using pharmacological techniques to identify the molecules involved in associaitve and non-associative learning, as well as the molecules that regulate different phases of learning such as memory formation and memory retrieval. In addition, we are using fluorescent tracers and markers to map connections between cells in the olfactory system and to study physiological changes that occur in th the brain as a result of learning.
