Dr. Glenn Toney’s research lies at the intersection between neuroscience and cardiovascular biology.  Studies seek to improve treatment of cardiovascular diseases and stroke, which are the leading causes of death and disability worldwide.  Techniques in routine use include electrophysiology, immunohistochemistry, tract tracing, optogenetics, viral mediated gene transfer, mRNA/protein expression techniques, confocal/fluorescence microscopy, sympathetic nerve recordings and hemodynamic measures.  One funded project seeks to restore normal cardiovascular function in hypertensive subjects by correcting hyperexcitability of neurons that drive sympathetic nerve discharge to peripheral cardiovascular tissues.  Another project models obstructive sleep apnea and seeks to identify neuroadaptations to intermittent brain hypoxia.  Our goal is to determine which adaptations confer stroke neuroprotection and which may be neutral or detrimental to neuron survival.
