Welcome

The Department of Physiology in the School of Medicine at the University of Texas Health Science Center, San Antonio is renowned for its seminal contributions in many scientific areas including cardiovascular physiology, neurophysiology and the physiological basis of aging. Using sophisticated genetic and molecular tools, our scientists are unraveling the fundamental mechanisms that underlie tissue and cellular physiology; and how these processes are compromised in injury and disease.

Rheaclare Fraser, Ph.D., Wins Poster Presentation

Dr. Rheaclare Fraser recently won first place for the best postdoctoral poster presentation at the recent meeting of the “International Society for Serotonin Research” (ISSR) at Arabella in South Africa.  Dr. Fraser is a postdoctoral fellow in Dr. Lynette Daws lab.

Aging Decreases L-Type Calcium Channel Currents and Pacemaker Firing Fidelity in Substantia Nigra DopamineNeurons

Substantia nigra dopamine neurons are involved in behavioral processes that include cognition, reward learning, and voluntary movement. Selective deterioration of these neurons is responsible for the motor deficits associated with Parkinson’s disease (PD).  Aging is the leading risk factor for PD, suggesting that adaptations occurring in dopamine neurons during normal aging may predispose individuals to the development of PD.  See more.
