The brain uses complex and highly parallel computational paradigms to process sensory information, create and retrieve memories, and execute motor actions. The unit of this computing network is the neuron and its attendant synaptic connections. The structure and physiology of the brain makes direct study of these structures in the living organisms very difficult – neurons and synapses are tiny, very delicate, and tightly packed. Our laboratory is dedicated to the study of how neuronal circuits create behavior. However, to truly understand how the brain functions it will be necessary to develop new methods that allow the study of the functioning brain in a less invasive more informative way.
My laboratory develops and uses novel imaging techniques to study neuronal electrophysiology. We are developing genetically-encoded fluorescent probes of membrane potential. These probes are introduced into neurons as DNA constructs which will make the neuron fluorescent. This fluorescence is then modulated by the electrical activity of the neuron. We can use high speed imaging to simultaneously monitor the activity of large numbers of neurons which were previously inaccesible.
Development of genetically-encoded fluorescent probes of membrane potential – this project involves the screening of DNA constructs encoding fusions of voltage sensing protein domains with fluorescent reporters. Testing of constructs is performed in cell lines and hippocampal neurons.
Development of miniature fluorescence microscope systems for imaging fluorescent probes in vivo in rodents – we are designing a complete head-mountable, fast imaging system to image voltages signals in behaving rodents.
Identification of fluorescent proteins from the marine environment – we are searching the marine environment (coral reefs) for novel fluorescent organisms as a means of finding superior fluorescent reports for use in the laboratory.
