Information in the nervous system is encoded by the timing and patterns of the action potentials that are generated by neurons. Uncovering the mechanisms that control these events is key to understanding brain function. For a particular neuron, electrical signals result from the interplay synaptic mechanisms that encode trans-neuronal signals with the ion channels and regulatory elements that determine the neuron's intrinsic excitability.
Listed below you will find links to descriptions of our ongoing research projects that focus on two key elements in neuronal signaling; potassium channels and neurotransmitter receptors. In addition, we describe our studies on a novel mechanism for regulation of neuronal signals.
