It has proven difficult to link the myriad proposed features leading to the cardiac and respiratory decline in sudden unexplained death in epilepsy (SUDEP). This project aims to identify a specific neuronal subtype in a deep brain nucleus which may be critical in cardiorespiratory control, providing a better understanding of the mechanism of SUDEP. The goal is first to identify that these neurons control cardiorespiratory functions and characterize them. Finally, we will verify that these neurons are activated in a genetic model of epilepsy in the hopes that further examination of these neurons might provide a potential therapeutic target to prevent SUDEP.
