Welcome to the Department of Neurobiology,
Physiology, and Behavior at UC Davis
Our mission is to extend knowledge, through our research,
into the understanding of vital functions common to all animals,
and to convey our knowledge and expertise in this area to our
students. All animals perform certain basic functions-they grow,
reproduce, move, respond to stimuli and maintain homeostasis. The
physiological mechanisms upon which these functions depend are
precisely regulated and highly integrated, but may be disrupted by
disease, injury and aging. Actions of the nervous and endocrine
systems determine behavior and the interaction between organisms
and their physical and social environments. Exercise and physical
activity also regulate the physiological, biomechanical and
behavioral aspects of the organism.
The research and teaching missions in the Department focuses
on functional mechanisms; the control, regulation and integration
of these mechanisms; and the behavior that relates to those
mechanisms at the level of the molecule, the cell, the organ
system and the organism, including at the human ecological level.
