In this episode of Mommy Brain Revisited I talk with Katie Haigler, a graduate student at Penn State, about her research detailing how the maternal brain processes infant and adult emotion cues - aiding in our understanding of emotion regulation in parents. Interesting!For more about Katie’s research seehttps://hhd.psu.edu/contact/katherine-haigler Here is a direct link to the paper we talk about.

In this episode of Mommy Brain Revisited I talk with Prof Wendy Saltzman, who is in the Department of Evolution, Ecology, and Organismal Biology at the University of California, Riverside.

In this episode of Mommy Brain Revisited, I talk with Dr Darby Saxbe, Professor of Psychology at USC Dornslife. We talk about her recent work on how brain changes in fathers may reflect parenting engagement and mental health risk. Fascinating!

In this episode of Mommy Brain Revisited I talk with Dr Susana Carmona, Research Scientist at the Instituto de Investigación Sanitaria Gregorio Marañón in Madrid, Spain. We talk about her recent research on how a mother’s brain changes from late pregnancy to the early postpartum published in Nature Neuroscience early this year. Fascinating research and the first of its kind! For more about Dr Carmona see: https://neuromaternal.es/ Her book is available in Spanish and titled: Neuromaternal: ¿Qué le pasa a mi cerebro durante el embarazo y la maternidad?.

In this episode of Mommy Brain Revisited I talk with Dr Nicolas Renier, the Team Leader of the Laboratory of Structural Plasticity at the Paris Brain Institute. We talk about his work on the neural mechanisms modulating nest building in mice during pregnancy. A fascinating study with amazing neuroscience techniques. We also talk about the value of using pregnancy as a model to understand neurophysiological processes, the important role of pregnancy in remodeling certain parts of the brain, what progesterone can do to neurons and more. Fascinating! For more about Dr Renier see: www.renier-lab.com Link to paper Paper citation: Topilko T, Diaz SL, Pacheco CM, Verny F, Rousseau CV, Kirst C, Deleuze C, Gaspar P, Renier N.

In this episode of Mommy Brain Revisited I talk with Dr Shir Atzil an Assistant Professor at the Hebrew University of Jerusalem. We discuss her recent Perspective in Nature Human Behaviour titled ‘Growing A Social Brain’. A must read! We talk about the importance of a caregiver or caregivers in growing a social brain, what happens when infants are more challenging or parents are struggling, and the fact that the parental brain is actually in charge of two brains. You won’t want to miss this one!

In this episode of Mommy Brain Revisited I talk with Dr Catherine Preston, an Associate Professor at the University of York. We talk about body sensations in pregnancy, trusting your perinatal body, bonding to bump, birth experience, and more. We also talk about the need to focus our research on pregnancy and importance of understanding the connection between interoception and the maternal brain in health and illness.

In this episode of Mommy Brain Revisited I talk with Dr Danielle Stolzenberg, an Associate Professor at UC Davis, about the nonhormonal basis of parenting, modelling perinatal mental illness, and the 51 Foundation which she started. We also talk about the need to understand current treatments for perinatal mental illness (particularly SSRIs) and the importance of funding research in females. Yes!
