Choreography between hormones and the brain key to understanding how women adapt to motherhood, says study

Researchers from the Universitat Autònoma de Barcelona (UAB), the Gregorio Marañón Health Research Institute and the Hospital del Mar Research Institute have published the first paper that reviews the scientific literature on the neurobiological adaptation occurring during pregnancy and postpartum in humans and other animals.

, i.e., the cognitive and emotional processes necessary to develop a mother-child relationship that adapts to the different phases of pregnancy and postpartum. This third factor is what most differentiates humans from other animals and little is known about it.Based on the evidence published, the researchers point out which neuroplasticity processes most likely contribute to the changes identified, and how these can be related to pregnancy and maternal behavior hormones.

A second line should work towards describing the mechanisms by which sexual hormones, especially estrogens, bring on the changes detected in structural and behavioral reorganization. Given the hormonal environment existing during the pregnancy and postpartum period and the interactive nature of these molecules, it is most likely that these changes are the result of a complex exchange of steroids and hormonal peptides.

Researchers uncover 'circular logic' of RNAs in Parkinson's diseaseResearchers are gaining new insights into neurological diseases by studying circular RNAs (circRNAs) in brain cells. A new study by investigators from the Brigham and Women's Hospital identified over 11,000 distinct RNA circles that characterized brain cells implicated in Parkinson's disease and Alzheimer's disease. Their results are published in Nature Communications.
