A study from the University of Essex found that insecure attachment traits in mothers can lead to increased brain-to-brain synchrony with their children. Father-child brain-to-brain synchrony may be a compensating strategy for a relative lack of behavioral synchrony. This research aims to improve understanding of parent-child relationships and develop interventions to support positive attachment development.

A new study from the University of Essex has revealed that parent-child synchrony may not always be beneficial for attachment development. In fact, the study found that insecure attachment traits in mothers may actually lead to increased brain-to-brain synchrony with their children. Led by Dr.Trinh Nguyen and Dr.Melanie Kungl, along with colleagues from Austria and Germany, this research aims to shed light on the complexities of parent-child relationships.

Previous studies have shown that parent-child synchrony can have both positive and negative effects on attachment development.

The study, published in the journal Developmental Science, focused on 140 families and examined how they interacted while completing puzzles together. The parents were also assessed for attachment using an interview, while the children underwent a story completion task. Brain activity was measured using functional near-infrared spectroscopy (fNIRS) while the parent-child interactions were video-recorded and coded for behavioral synchrony.

Secure attachment is crucial for healthy emotional and social development in children.

The results of the study showed that mothers and children had stronger behavioral synchrony while fathers and children had stronger brain-to-brain synchrony. This suggests that father-child brain-to-brain synchrony may be a neural compensation strategy to counteract a relative lack of behavioral synchrony. However, the researchers cautioned that high synchrony may also be a sign of interaction and relationship difficulties, not just low synchrony.

Insecure attachment in parents may make it more difficult to achieve optimal behavioral synchrony with their children.

The research team hopes that this study will lead to further investigations into parent-child relationships, as well as potential interventions and prevention strategies. Dr.Pascal Vrticka, one of the co-authors of the study, will be working with the NHS to explore this topic further, particularly with families of children with neurodivergent and adoption experiences. By understanding the optimal range of synchrony, researchers hope to improve relationships and attachment development in all families.

Brain-to-brain synchrony is a neural mechanism that can compensate for less attuned interactions between parents and children.

In conclusion, this study highlights the complexity of parent-child synchrony and its impact on attachment development. It also emphasizes the importance of understanding attachment and developing interventions and strategies to support healthy relationships within families.



The Surprising Link Between DNA, Inflammation, and Long-Lasting Memories

A new study suggests that breaking and repairing DNA in neurons may pave the way for long-lasting memories. Surprisingly, inflammation in certain neurons in the brain’s hippocampal region is essential for making these memories. The hippocampus is a key brain region for encoding memories, and scientists have long believed that rewiring the brain's connections is a fast and unstable process. However, the study found that a subset of neurons alter their connections to encode long-lasting memories, by recruiting proteins that usually fight off bacteria and cause inflammation. This process, called synaptic plasticity, allows for rapid changes in overall neural connections and helps memories form.

A team at the Champalimaud Foundation has discovered the role of “zombie neurons” in the cerebellum's critical teaching signals. These neurons, alive but functionally altered, have helped to advance our understanding of the cerebellum's role in associative learning. By manipulating them in mice, the researchers were able to induce changes in behavior, shedding light on the intricate mechanisms involved in learning. This could have implications for rehabilitation strategies and further our understanding of psychiatric disorders linked to the cerebellum.

Psychedelics have shown potential in rapidly reducing negative affective bias - a common feature of depression. A new study found that ketamine and psilocybin can rewire brain circuits and shift emotional states, leading to lasting effects. The drugs' ability to promote neural plasticity and the birth of new neurons may explain their fast-acting nature. Despite being commonly seen as party drugs, psychedelics are gaining recognition in the medical community for their potential in mental health therapy.

Our research into the biological root of arithmetic has led us to believe mathematics is a realization in symbols of the fundamental nature and creativity of the mind. We explored the behavior of bees to gain insight into this, as they can take a meandering journey to find nectar and then return by the most direct route. We showed that the abilities of bees in returning to the hive suggested principles that could be used to explain simpler arithmetic operations. Our study brings together the insights from the psychologist Jean Piaget and the mathematician Jacques Hadamard.

In a recent research published in eLife, how bees make complex decisions and outperform humans and primates was studied by analyzing the behavior of bees in an array of artificial flowers. Researchers found that bees take a risk-averse strategy whereby they only accept a flower if they are sure it is rewarding, and reject if they are uncertain. This allows them to make decisions much quicker and beat the speed accuracy tradeoff.
