Research Interest

The primary research goal of our laboratory is to understand the cellular and molecular mechanisms that regulate neuronal excitability and the efficacy of synaptic transmission. Our experimental approach uses primary neuronal culture, brain slices, and patch-clamp electrophysiology, in combination with molecular biology and histological techniques, to examine modulation of ion channels, neurotransmitter receptors, and synaptic circuits. One of our current projects involves determining the cellular and molecular basis of circadian rhythms in the olfactory system. We are exploring how electrical synapses formed by gap junctions and rhythmic expression of monoamine neurotransmitters (norepinephrine, dopamine, serotonin, and melatonin) contribute to rhythmic regulation of synaptic circuits underlying odor information processing. Other projects include investigating the role of zinc as a neuromodulator and the function of circuits of the hippocampus, hypothalamus, and amygdala.
