Research Interests:

Animal models of human developmental illnesses.

Current Research:

Dr. Whitaker-Azmitia is a neuropharmacologist interested in brain development, in particular what is different in development which leads to disorders such as autism. Neurotransmitters such as serotonin and hormones such as progesterone and cortisol play a role.  Although past work has focused almost entirely on animal models (including the rat model of developmental hyperserotonemia developed in this lab) currently Dr. Whitaker-Azmitia is working more with human subjects and using that information to develop better animal models.

In human illnesses such as autism, animal models can not only verify etiologies, they can also be used to test treatments Continuously modifying models is essential to new discoveries. For example, research on obstetrical factors has led to our recently published hypothesis that low levels of progesterone during development will lead to an increased incidence of autism.  To further test this hypothesis, an animal model of lowered progesterone will be developed.  Furthermore, women who perceive more stress during pregnancy are also more likely to give birth to a child with autism – and a model of prenatal stress will be used in animals to determine whether or not autism-like behaviors and neurochemistry result.
