Dr. Leiter is interested in the neurophysiology of respiratory control, central chemosensitivity and Sudden Infant Death Syndrome. He is interested in the role of astrocytes in all of these topics. Additional interests include the neurobiology of deep brain stimulation in Parkinson’s Disease and psychiatric disorders.
Rotations and Thesis Projects:
There are current opportunities to work studying interactions among central chemosensitivity and the laryngeal chemoreflex as it pertains to SIDS. They are examining the role of serotonin and adenosine in the modulation of these reflex responses. We are using lentiviral vectors to alter astrocytic functions and thereby alter cardiorespiratory reflex control of autonomic function.
In respect to deep brain stimulation, we are studying the role of DBS in movement disorders and substance abuse. A strong background in engineering and mathematics is helpful in these studies.
