Research Statement

The focus of research in the Lonstein lab is to better understand the neurobiology of parenting and postpartum emotional state in mammals.  Non-postpartum females of most species do not act very maternally toward infants, although a dramatic change in responding occurs after females are pregnant and their infants are born. Research in the Lonstein lab is devoted to understanding how the hormones of pregnancy and lactation alter neurochemistry in the laboratory rat brain to promote nurturant behaviors towards infants. 

A related area of research is devoted to studying how reproductive state and physical contact with offspring postpartum modulate female neurochemistry in a way that affects anxiety.  We are particularly interested in how infant contact modulates the maternal noradrenergic, GABAergic and serotonergic systems to supress the mother's anxiety and optimize her display of caregiving behaviors.

Adequate and appropriate maternal responding is critical for the normal development, if not survival, of offspring. Understanding the parental brain, therefore, has clear implications for non-human development as well as for human welfare.

Lonstein Lab We are interested in the neural and hormonal regulation of maternal behaviors and changes in emotional regulation during lactation, as well as the regulation of sex differences in social behaviors and the brain in monogamous voles.
Mother and Babies Study Does stress during pregnancy affect women's and infant's physical and emotional health? Our research examines whether relationship conflict is a stressor that works like other stressors by affecting the body's stress system and emotional responses to stress. We are recruiting 160 women and their one-year old children. The women will include those with and without relationship conflict during pregnancy and those with and without relationship conflict during the first year of the child's life. Looking at differences among these women and children will allow us to understand how relationship conflict affects women and children at different times in their lives.
