In this episode of Mommy Brain Revisited, Dr Tim Oberlander and I briefly discuss SSRI use in pregnancy and the importance of focusing on maternal mental health in this area of research.

Our conversation centers on our perspective, Potential risks and benefits of prenatal selective serotonin reuptake inhibitor medications for maternal mental health and child development published in Nature Mental Health.

We emphasize the complexity of separating medication effects from underlying maternal depression and the importance of comprehensive approaches, including pharmacologic and non-pharmacologic treatments.

Dr. Tim Oberlander has over 3 decades of research on maternal mental health, SSRIs and child development. He is a Developmental Pediatrician, Clinician-Scientist and Professor of Pediatrics in the School of Population Public Health, University of British Columbia and BC Children’s Hospital.

In this episode, I sit down with Danielle S. Stolzenberg, Ph.D. , Associate Professor in the Department of Psychology at the University of California, Davis, whose work explores the neuroscience of care.

Dr. Stolzenberg shares insights from her emerging research on psychedelic compounds in the postpartum period, examining how substances like psilocybin may influence maternal stress, bonding, and brain plasticity.

Whether you’re interested in neuroscience, maternal health, or the rapidly evolving field of psychedelic science, this conversation provides a grounded and thought-provoking look at what we know—and what we still need to learn—about psychedelics postpartum.

Welcome to another episode of Mommy Brain Revisited! In this episode, I’m joined by Prof. Joseph Lonstein (Michigan State University) to talk about our recent research on how probiotic treatment shapes the maternal gut–microbiota–brain axis.

This work—published in the Journal of Neuroendocrinology as part of the Parental Brain Special Issue—explores how reproductive experience influences the effects of Lactocaseibacillus rhamnosus HN001 on gut microbiota and hippocampal plasticity in female rats:

In this episode of Mommy Brain Revisited, I’m joined by Dr. Mariana Pereira, an Associate Professor at UMass. We dive into the maternal affective state and mother-offspring interactions in an animal model of depressive-like behavior. We also talk about dopamine, maternal mental health and treatment strategies. Tune in for a fascinating conversation on brain changes with maternal mood!

For more about Dr Pereira's research, see here.

Pregnancy isn’t just about a baby bump—it’s also a massive hormonal and physiological shift, including how the body regulates temperature.

In this episode of Mommy Brain Revisited, I’m joined by Dr. Rosie Brown, a Senior Lecturer and Group Leader at the University of Otago in New Zealand. We dive into the hormone prolactin—its role in motherhood and the brain—and explore her team’s groundbreaking research on how prolactin helps regulate body temperature during pregnancy. Tune in for a fascinating conversation on all things prolactin and parenting!

In this episode of Mommy Brain Revisited I talk with Prof Dr Natalya Chechko, a specialist in psychiatry and psychotherapy at Aachen University.

We talk about her recent research investigating maternal brain changes and mental health. We also talk about the neuroendocrine factors that may be involved and how to visualize them in the human brain. Fascinating research! Enjoy.

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!

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.

We talk about her research detailing how caregiving affects the paternal brain and how fascinating parenting is in many species!
