Pondering the Caregiver Environment and Development of Social Skills in Infants with Maya Opendak

The environment and experiences of caregivers can affect the development of social skills in the infants they care for in ways that can result in enduring changes in behavior patterns. In this episode neuroscientist Maya Opendak at Johns Hopkins University talks about her research using experimental models of deprivation and adversity which is shedding light on the brain circuits altered by deprivation and maternal stress and the cellular and molecular mechanisms underlying those alterations.  Such fundamental information will be required to fully understand and therefore work towards optimization of the early life environments of infants and their caregivers.
