Position Description: 

Projects focus on the mechanisms underlying neuronal activity using GnRH neurons as the model system. In vivo, GnRH neurons, spread throughout the forebrain, release GnRH in a pulsatile fashion to control reproduction. In explants, primary GnRH neurons continue to release in a pulsatile fashion and show synchronized calcium oscillations. Projects utilize the GnRH system to study molecular and cellular properties of neuronal activity (individual cells and neuronal population dynamics) and correlate activity with secretion.
