My lab and I are interested in how the mammalian brain processes and remembers information. As a model system we focus on rodent (rats and mice)  discrimination and memory for odors.  Using electrophysiological, behavioral, genetic, neuroanatomical and pharmacological approaches we explore the neurobiology of memory and the role of experience in sensory system function.  The underlying hypothesis of much of our work is that memory plays a critical role in even basic sensory discrimination. That is, your perception of the world is not static but reflects your past experiences. Some specific questions we are addressing include: how does sensory experience shape odor discrimination?; how does sensory encoding reflect hedonic/emotional associations of odors?; what role does sleep play in olfactory perceptual learning?; how do local neural circuits and larger regional networks interact to shape perception and memory? In addition, we are interested in how experience early in life (Fetal Alcohol Spectrum Disorder), or aging and dementia (Alzheimer's disease) can influence sensory system function.  Our current research is funded by the National Institutes of Health.

ensemble data

The ability of neural ensembles in the primary olfactory sensory cortex (piriform cortex) to distinquish between complex overlapping mixtures of odors varies with behavioral ability to discriminate those mixtures. Rats were training in a two alternative forced choice task (Left). Ensembles in naive rats decorrelate some but not most mixtures (pseudocolor plot left).  After initial training, but while still performing at chance levels, cortical ensemble lose the ability to decorrelate most mixtures (pseudocolor plot top).  However, with successful training and good behavioral performance, ensembles now decorrelate all overlapping mixtures (pseudocolor plot right).  From Chapuis & Wilson, 2012.
