What would it be like if your neurons could regenerate?

  What If Neurons Could Regenerate? Imagine a world where your brain could heal and renew itself like your skin or liver. How would that change your life? Would you still be the same person, or would you evolve into someone entirely different? Let’s dive into this mind-bending idea together. The top image shows fluorescently labeled cells in the spinal cord of a zebrafish recovering one week after an injury, and the bottom image shows recovery four weeks after an injury. Researchers at Washington University School of Medicine in St. Louis describe the dramatic changes within nerve cells that make regeneration possible. Such findings could inspire the development of new therapies for spinal cord injuries in people.

Learning could become faster and more efficient, making knowledge ret...

Mind Meets Body: Unlocking the Secrets of Brain–Body Communication By Arya Bandyopadhyay | Exploring the Mind–Body Code Your body and brain are in constant dialogue. Far from being a one-way system, this relationship is dynamic and bidirectional—your brain listens, learns, and rewires itself based on feedback from the body. Understanding this intricate network opens doors to rethinking health, emotion, and disease. 1. The Brain Listens: Vagus Nerve & Organ Signals Illustration of the vagus nerve, highlighting its pathway and connection to vital organs, influencing the autonomic nervous system.

Gut microbes, for example, help produce neurotransmitters that affect your mood. “Your second brain—the gut—has more power than you think.” 2.

Analysis of nearly 2,000 people living in remote villages in Honduras reveals who’s spreading gut microorganisms to whom. Friends share more than just food when they dine together.Credit: Getty A shared meal, a kiss on the cheek: these social acts bring people together — and bring their microbiomes together, too. The more people interact, the more similar the make-up of their gut microorganisms is, even if individuals don’t live in the same household, a study1 shows. The study also found that a person’s microbiome is shaped not only by their social contacts but also by the social contacts’ connections. The work is one of several studies2 that raise the possibility that health conditions can be shaped by the transmission of the microbiome between individuals, not just by diet and other environmental factors that affect gut flora. In the quest to understand what shapes a person’s microbiome, social interactions are “definitely a piece of the puzzle that I think has been missing until rec...
