Research Abstract

Our laboratory studies potassium channels which are key elements which control and shape electrical activity in the brain, heart, and other excitable tissues. These channels are major determinants of behavior and higher brain function. The potassium channels we study are involved in human disease (e.g. epilepsy, cardiac arrhythmia), basic physiology (e.g. control of blood pressure, protection from hypoxia), and higher brain function (e.g. learning and memory). Our approach is a comparative genomic one which involves comparing the structure and function of potassium channels in different species (e.g. humans, rodents, Drosophila and the nematode worm C. elegans). These comparisons have led us to many fundamental insights about the basic function, development, and regulation of potassium channels, and their role in behavior... read more
