The Association Between Prenatal Maternal Stress, Infant Brain Volumes, And Temperament During The Covid-19 Pandemic, Amber L. Di Paolo
The Association Between Prenatal Maternal Stress, Infant Brain Volumes, And Temperament During The Covid-19 Pandemic, Amber L. Di Paolo
Electronic Thesis and Dissertation Repository
Prenatal maternal stress (PNMS) is associated with altered trajectories of infant socio-emotional and brain development, including brain structures such as the amygdala and prefrontal cortex (PFC). During the COVID-19 pandemic, which was a major global stressor, PNMS was significantly elevated, yet the impact on infant neurodevelopment remains uncertain. The objective of the present study was to determine whether PNMS during the pandemic was associated with infant amygdala and PFC volumes as well as temperament. In addition, we examined whether social support and resilience during pregnancy were protective factors.
Participants were enrolled in the Canadian ‘Pregnancy during the COVID-19 Pandemic’ cohort …

Exploring The Neural Basis Of Top-Down Guided Action In Macaque Monkeys, Jessica M. Phillips
Electronic Thesis and Dissertation Repository
To thoroughly characterize any brain mechanism requires an appropriate animal model for invasive studies. An invaluable model system used toward a comprehension of cognitive neurophysiology is the macaque monkey. It is important to delineate similarities and limitations for this model in relation to the human brain and cognition. In this thesis, we have thus conducted three experiments to investigate putative generalizations between monkeys and humans regarding the neural processes associated with top-down action control in monkeys.
Our daily behaviour is largely comprised of automatic routine actions. The frequent repetition of certain behaviours in response to particular contexts can give rise …
