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.

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!

In this episode of Mommy Brain Revisited I talk with Dr Maria Muzik and Dr. Katherine Rosenblum about Mom Power, a parenting intervention they developed, and how it impacts parents and the parental brain. Both are Professors in the Departments Psychiatry and Obstetrics & Gynecology, as well as Co-Directors of Zero To Thrive & Women and Infant Mental Health Program at the University of Michigan. We talk about the development of Mom Power, it’s core components and the research supporting the importance of this group intervention. We also talk about attachment, the importance of nature, and building ‘strong roots’. It was an honor to speak with these two inspiring clinician-scientists. If you work with parents, this episode is a must.

In this episode of Mommy Brain Revisited I talk with Dr Jonny Kohl, Group Leader, State-Dependent Neural Processing Laboratory, The Francis Crick Institute, London, UK. We talk about his new research on how the hormones of pregnancy affect specific neurons in the MPOA that essential for parenting. It’s a fascinating new finding and provides valuable insight into the neuroendocrine factors governing parental care. We also talk about whether or not we should be using reproductively experienced females more in general neuroscience research because of the long-term impact of pregnancy on the brain, the importance of state in general and practical considerations for doing these types of studies. It’s a good one. You won’t want to miss it.

In this episode of Mommy Brain Revisited I talk with Dr. Pascal Vrticka, Associate Professor and Senior Lecturer in Psychology at the University of Essex. We talk about all thing’s attachment and neural synchrony in mother-child and father-child dyads. We also talk about attachment parenting and how our beliefs about parenting can impact how our brain functions. Fascinating! Don’t miss this episode of Mommy Brain Revisited. It will make you rethink about how the parental brain is working and why!
