• Multitasking Amygdala Neurons Respond to Sights, Sounds, and Touch

    A recent study by Dr. Katalin Gothard and colleagues looked at how amygdala neurons that respond to touch also respond to imagery and sounds. These cells may provide the building blocks needed to process multi-sensory social and emotional information.

  • Reconnecting the Disconnected: UA Physiology Professor Receives $1.2M NIH Grant to Use AI to Restore Movement in Paralyzed Limbs

    When a person is paralyzed by a stroke or an injury, the brain and the neuron networks that control movement become disconnected from the muscles. Dr. Andrew Fuglevand is using artificial intelligence to stimulate multiple muscles to elicit natural movement in ways previous methods have been unable to do.

  • UA Physiology Researcher Continues Studies on Nicotine Exposure During Pregnancy with $1.9 Million NIH Grant

    Although the numbers of nicotine patch and electronic cigarette users during pregnancy are increasing, new research suggests the use of nicotine-replacement therapy is an unsafe alternative to cigarettes. This five-year NIH grant will allow UA physiology researcher Dr. Ralph Fregosi to continue his studies on the short- and long-term developmental risks of nicotine exposure to pre- and post-natal health.


Welcome from the Department Head

Welcome to the Department of Physiology at the University of Arizona. We offer and participate in courses and programs for undergraduate, graduate, and medical students. The Physiology major is one of the most popular choices for UA undergraduates, and is the only undergraduate major offered through the College of Medicine.
