The concept of consciousness has long captivated the minds of philosophers and scientists alike, yet its true origin remains shrouded in mystery. In recent years, neuroscientists have made significant strides in understanding the neural underpinnings of consciousness. Through studying the brain's complex network of connections and electrical signals, researchers have begun to decipher how these processes give rise to conscious experiences and our sense of self .

Previous attempts to explain the origin of consciousness have resulted in fragmented theories and contradictory ideas.

Exploring the Impact of Parent-Child Synchrony on Attachment Development

Category Neuroscience

tldr

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.

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

Category Neuroscience

tldr

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.

Uncovering the Role of “Zombie Neurons” in Cerebellar Learning

Category Neuroscience

tldr

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.

Key Step in Tau Tangle Development Identified by Researchers

Category Neuroscience

tldr

Researchers have identified a key step in the development of destructive tau tangles, which are responsible for brain diseases known as tauopathies. By targeting this step and studying the role of long noncoding RNAs (lncRNAs), scientists hope to find new therapeutic approaches for these devastating conditions. One particular lncRNA, SNHG8, has been found to play a role in regulating tau protein aggregation and shows potential as a target for intervention.

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.
