Dr. Stanton is engaged in work across the range of neuronal plasticity. His group was the first to show that induction of long-term potentiation of mammalian synapses requires cyclic AMP and new protein synthesis. Current projects utilize slices from hippocampus and neocortex to examine changes in synaptic function associated with the development of epileptic seizures and identify cellular mechanisms that both trigger and prevent ischemia-induced delayed neuronal death.

For 20 years, my lab has been engaged in work across the range of neuronal plasticity, including: 1) properties of long-term activity-dependent potentiation (LTP) and depression (LTD) of synaptic strength; 2) links between LTD and cascades underlying LTP; 3) changes in synaptic function associated with the development of epileptic seizures; and 4) cellular mechanisms that both trigger and prevent ischemia-induced delayed neuronal death. We were the first to show that induction of mammalian LTP requires cyclic AMP and new protein synthesis, and to demonstrate a novel form of LTD evoked when presynaptic inputs are active while postsynaptic neurons are hyperpolarized. This led to our describing a NO-mediated cyclic GMP-dependent biochemical cascade that is part of bi-directional cyclic nucleotide regulation of synaptic strength, discovering chemical methods of inducing this and other forms of LTD, and direct two-photon fluorescence imaging of presynaptic transmitter release to demonstrate that this form of LTD persistently modulates release from the rapidly-recycling pool of transmitter vesicles. We employ extracellular and whole-cell patch clamp recordings, two-photon excitation and confocal fluorescence imaging in both acute and organotypic cultures of in vitro slices from hippocampus and neocortex. As a more physiologically intact network of synaptically connected neurons and glia, brain slices are ideal for the study of cellular and synaptic properties of neural systems.
