Social bonding gets people on the same wavelength, neural synchronization study suggests

Posted by in category: neuroscience

When small hierarchical groups bond, neural activity between leaders and followers aligns, promoting quicker and more frequent communication, according to a study published on March 19 in the open-access journal PLOS Biology by Jun Ni from Beijing Normal University, China, and colleagues.

Social groups are often organized hierarchically, where status differences and bonds between members shape the group’s dynamic. To better understand how bonding influences communication within hierarchical groups and which are involved in these processes, the researchers recorded 176 three-person groups of human participants (who had never met before) while they communicated with each other, sitting face-to-face in a triangle.

Participants wore caps with fNIRS (functional near-infrared spectroscopy) electrodes to non-invasively measure brain activity while they communicated with their .

12,000-Year-Old Preserved Human Brains Defy Soft Tissue Decay Assumptions

Posted by in categories: biotech/medical, neuroscience

The human brain, it turns out, can be surprisingly resistant to the ravages of time.

A new study has cataloged human brains that have been found on the archaeological record around the world and discovered that this remarkable organ resists decomposition far more than we thought – even when the rest of the body’s soft tissues have completely melted away.

Led by molecular taphonomist Alexandra Morton-Hayward of the University of Oxford, a team of scientists has identified more than 4,400 preserved human brains, dating back as far as 12,000 years ago. The results contradict previous evidence that the human brain is among the first organs to decay after death.

Your Blood Could Be Aging Your Brain, Increasing Risk of Dementia

Posted by in categories: biotech/medical, life extension, neuroscience

Our brains change more rapidly at various times of our lives, as though life’s clock was ticking faster than usual. Childhood, adolescence and very old age are good examples of this.

Yet for much of adulthood, the same clock seems to tick fairly regularly. One lap around the Sun; one year older.

However, there may be a stage of life when the brain’s clock starts speeding up. The brain starts changing without you necessarily noticing it. It may even be caused (partly) by what’s in your blood.

Astrocytes Remember: A New Layer of Immune Memory Uncovered

Posted by in categories: biotech/medical, genetics, neuroscience

Researchers have made a pioneering discovery that astrocytes, cells within the central nervous system traditionally not associated with immune functions, are capable of developing what’s being called an “immune memory.” This capability…


Summary: Astrocytes, traditionally non-immune cells within the central nervous system, possess the ability to develop an immune memory, responding more vigorously to subsequent immune challenges. This groundbreaking study reveals that through an epigenetic mechanism involving the enzymes p300 and ATP-citrate lyase (ACLY), astrocytes enhance their pro-inflammatory responses, a trait similar to the immune memory seen in adaptive immunity.

The findings, which have been observed in both mouse models of multiple sclerosis (MS) and human cell samples, suggest that astrocyte immune memory may play a significant role in chronic neurological disorders, offering new insights into disease pathology and potential therapeutic targets to mitigate CNS inflammation.
