Maternal Love: How a Mother’s Brain Responds to Her Infant

29.02.2008
The distinctive ability of mothers to identify the cries of their offspring is widely evident in nature, where it is critical to the survival of these offspring.

In humans, we are aware that the distinctive ability of mothers to recognize and respond to the smiles and cries of their babies plays an important role in the psychological, cognitive, and social development of these babies. We have had a very limited understanding of how the maternal brain accomplishes these amazing feats, but a new study published in the February 15th issue of Biological Psychiatry now provides some new insight.

Noriuchi, Kikuchi, et al. used functional magnetic resonance imaging (fMRI), a tool that enables scientists to study the function of brain circuits in people, to examine patterns of maternal brain activation. The authors asked healthy mothers to view video clips, which showed either their own infant (approximate age of 16 months) or an unknown infant in two emotional conditions – either happy or upset/crying. Dr. Madoka Noriuchi, senior author on the paper explains their findings: “We found that a limited number of mother’s brain areas were specifically related to maternal love, and the specific pattern of mother’s response was observed for her infant’s attachment behaviors evoking mother’s care-taking behaviors for vigilant protectiveness.”

In other words, they discovered that particular circuits in the brain, involving several regions in the cerebral cortex and limbic system, are distinctively activated when mothers distinguish the smiles and cries of their own infants from those of other infants. The authors also found that a mother responds more strongly to the crying than the smiling of her own infant, which, according to the authors, seems “to be biologically meaningful in terms of adaptation to specific demands associated with successful infant care.”

John H. Krystal, M.D., Editor of Biological Psychiatry and affiliated with both Yale University School of Medicine and the VA Connecticut Healthcare System, discusses the importance of this study: “This type of knowledge provides the beginnings of a scientific understanding of human maternal behavior. This knowledge could be helpful some day in developing treatments for the many problems and diseases that may adversely affect the mother-infant relationship.”

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
