Research Theme

The adult male offspring exposed to prenatal stress (PNS) spend less time on the open arms of the elevated plus maze (EPM) than control males, indicating greater anxiety-like behaviour.

It is widely accepted that an individual is shaped by a combination of nature and nurture. The implication is that the way in which an individual responds to stress is not solely a consequence of their genetic make-up; rather, it is defined by how their genes interact with their pre- and post-natal environment.

The perinatal period (the time before and after birth) is a time of marked neural plasticity; hence, brain development is susceptible to re-modelling. Adverse experiences in early life, such as stress exposure, can permanently ‘programme’ physiological systems and behaviours. Often this programming of the brain is maladaptive, increasing the susceptibility of the offspring to various diseases. 

Our research has demonstrated that maternal exposure to social stress during pregnancy is linked with low birth weight, anxious behaviour, hyperactive stress axis activity, insulin resistance, cognitive deficits and abnormal social and behaviours in the offspring. We investigate the mechanisms in the brain that underpin these changes and whether the impact of stress exposure during development can be prevented or reversed. 

Current projects are focused on understanding:

  • The central mechanisms involved in fetal programming of the brain and behaviour following prenatal stress exposure.
  • The mechanisms involved in transmission of maternal stress effects from the mother to the fetus.
  • The role of the gut microbiota in stress axis dysfunction and anxiety behaviour in prenatally stressed rats.
  • The short and long term impact of painful/stressful husbandry practices in early life in pigs (e.g. tail docking, tooth resection) on the brain and behaviour.
