New research led by Stanford Medicine challenges the long-held idea that the brain developed from a single ancestral system. Scientists say the human brain contains two ancient nervous systems that evolved independently before becoming integrated into one organ — one controlling vital functions such as breathing and heartbeat, and another supporting complex human abilities such as language, mathematics and abstract thought.

New brain discovery could aid neurological disease studies 

A study has revealed that the human brain is not one, but two separate organs. Scientists from Stanford University noted that the human brain consists of two ancient nervous systems that evolved separately. Today we have the hindbrain and the higher brain that work together. While the former helps us breathe, sleep and regulates our heartbeat, the forebrain and midbrain, part of the hindbrain, are linked to higher-level thinking, such as language, consciousness and abstract reasoning.&nbsp;The two parts of the brain were two distinct organs, developing independently of each other millions of years ago. This is similar to the jellyfish that have two nervous systems. Dr Kyle Loh, one of the authors of the study, said this is the first time they have shown that "the front of the brain arises from a totally different progenitor cell than the back of the brain."&nbsp;The study started because of a problem scientists have faced for years. They have never been able to grow human hindbrain neurons in the lab, which has hindered research on brain stem diseases, such as spinal muscular atrophy and ALS (amyotrophic lateral sclerosis). But generating forebrain cells hasn't been as difficult.&nbsp;They decided to watch exactly how the brain takes shape when the baby is still developing. For this, they examined developing mouse embryos and found that the development pathway in the case of the hindbrain was completely separate from the other regions of the brain. They express a gene called Otx2 in the forebrain and midbrain, while in the hindbrain they express a gene called Gbx2.<h2>Totally different packaging</h2>They also found different forms of DNA packaging between the regions. Dr Loh said they can now "grow neurons from the back of the brain, the hindbrain, in a petri dish and study their functions." Co-author Dr Rayyan Jokhai noted that previous attempts likely failed because scientists "tried to coax forebrain and midbrain progenitors into hindbrain cells", which is impossible, as shown by the latest study.&nbsp;The discovery led the team to create functional hindbrain motor neurons in the laboratory for the first time. The breakthrough will help study diseases like spinal muscular atrophy and ALS, as they now "have a model to better understand these devastating diseases."

The human brain continues to fascinate, as scientists have now revealed that we actually have two organs in our skull, not one. The brain is two separate organs, a study has found. The finding will help research conditions like ALS and spinal muscular atrophy.

A new study has shed light on how excess iron trapped inside neurons may contribute to brain cell damage and accelerate neurological decline. Researchers identified a process known as “chronoferroptosis,” in which iron accumulation gradually weakens neurons' natural defenses, making them more vulnerable to stress and injury over time. The findings offer fresh insight into how brain aging and neurodegenerative disorders may develop, while opening new avenues for research into treatments aimed at protecting brain cells and preserving cognitive function.

New research into brain activity shows that falling in love can activate regions linked to reward, motivation, and craving, similar to what is seen in substance addiction. Brain scans of young couples in the early stages of romance reveal heightened emotional responses and intense focus on their partners. Scientists say this may explain why love can feel overwhelming, obsessive, and deeply emotional, especially during the initial phase of a relationship.

A major new international study suggests that men’s brains may age faster than women’s challenging long-standing assumptions about brain ageing and Alzheimer’s disease.
Researchers analysed brain scans from more than 4,700 healthy adults and found greater brain shrinkage and decline across multiple regions in men. The findings raise new questions about why women are still nearly twice as likely to develop Alzheimer’s, despite slower overall brain ageing.
Experts say ageing alone does not cause Alzheimer’s, pointing instead to complex interactions between brain structure, inflammation, genetics and hormones. The study adds a new dimension to the global effort to understand how and why dementia develops.

After 9/11, the world couldn't stop talking about a person named Nostradamus. He was a French astrologer who lived in the 16th century and apparently predicted the terrorist attack on the Twin Towers in New York. He wrote about a "fire approaching a great new city", which people interpret to mean the aeroplanes that hit the World Trade Centre towers in the bustling American city. Baba Vanga is another mystic from Bulgaria who is believed to have had visions about the Chernobyl disaster, World War II, Princess Diana's death, the September 11 attacks, the 2004 tsunami and even her own death.

This memory also explains why we sometimes have a sudden feeling of having been to a place before, or the exact same things unfolding that feel like they have happened before.&nbsp;“Some people hypothesise that precognition is your brain entangled with itself in the future, because entanglement is not only things separated in space, but also separated in time,” Radin states. “If it can be entangled with itself in the future, in the present, you’d be feeling something like a memory that is going to happen in the future.” This explains not only precognition, but also déja vû and that feeling in the pit of your stomach.&nbsp; &nbsp;

It is common to feel something is about to happen even when you have no way of knowing it. This is believed to happen because our consciousness can possibly travel to the future, as in reality, time is not linear. This is why our brain has memories of things that have not happened yet.

Your Brain Changes When You Work Too Much. Research shows that working long hours, especially over 52 per week, can physically alter brain structure. A new study conducted in South Korea used MRI scans to compare brain volumes in healthcare workers. Those who were "overworked" had significant changes in regions responsible for decision‑making, memory, and emotional control.&nbsp;Overwork Linked to Brain Volume Increase Researchers at Chung‑Ang and Yonsei Universities compared 32 workers putting in 50+ hours per week to 78 with standard hours. They found around 19 per cent increase in volume of the left middle frontal gyrus, an area key to executive skills. Using voxel‑based morphometry, they noted similar increases in 17 brain regions, including the insula and superior frontal gyrus.<h2>What These Changes Mean</h2> While higher volume might look positive, experts say it could be the brain's response to chronic stress. It may temporarily boost focus, but long term side effects include fatigue, reduced emotional control, and can also lower cognitive ability. As of now this study's small size and health‑worker sample mean more research is needed.<h2>Why Work-Life Balance Matters</h2> This research adds to previous links between overwork and health problems, like stroke, heart disease and mental stress. Experts emphasise both individuals and employers need to act. Strategies include regular breaks, managing stress, and setting clear work‑hour limits.Dr Wanhyung Lee, who is co-author and assistant professor, states that organisations must support healthy work norms and not burden individuals to fix overwork alone.&nbsp;<h2>What You Can Do</h2>Take short breaks and stick to reasonable working hoursGet enough sleep, exercise, and rest.Employers should enforce decent workload limits and required mental health supportHealthy work habits can protect cognitive and emotional brain healthThis study is a warning: long working hours may lead to actual changes in your brain. Prioritising rest and balance can help preserve mental performance and emotional stability. Broader studies are needed; however, the early evidence is clear: overwork has real costs to brain health.

Working over 50+ hours a week can physically change brain structure, increasing volume in areas linked to decision-making and memory. While this may boost focus short-term, long-term effects include fatigue and reduced emotional control. Experts urge work-life balance for brain health.

Your brain may start 'eating itself' during extreme endurance exercise, study finds

A woman in the United States who was experiencing a burning sensation in her feet was shocked to know the strange reason for it. Doctors told the 30-year-old that there were parasites in her brain and this is what was causing this condition. The woman had been experiencing hot pain in her feet and legs. It extended to the trunk, her arms and then her head. She started having terrible headaches which did not alleviate despite consuming painkillers.
The woman's case study was published in the New England Journal of Medicine.

After returning home, it took 12 days for the parasites to start showing their effect on her body. She had an intense immune response and only a week after this were the doctors able to diagnose her problem.
When she started experiencing the pain in her feet, tests revealed a mild increase in disease-fighting white blood cells. She later started getting a fever and so decided to visit another hospital.

She was treated with intravenous anti-inflammatories and an anti-anxiety medication. Her headache subsided and she was discharged.
<h2>Confusion started setting in</h2>
But now the problem started showing up in a weird manner. The next morning she got up and started packing for a vacation, one that wasn't even planned. She looked confused and her roommate told her to rest. But since her condition did not improve, her partner took her to a hospital.
Her blood was tested once again and a CT scan of her head was also performed. No worms showed up in either of them. But then the staff performed a lumbar puncture and found that the cerebrospinal fluid (CSF), which covers the brain and spinal cord, had markers of eosinophilic meningitis. This condition is a rare form of brain infection that is caused by parasites.
<h2>Diagnosis on rat lungworm</h2>
Looking at her travel history and symptoms, the doctors made a presumptive diagnosis of angiostrongyliasis. Also known as rat lungworm, caused by the parasite Angiostrongylus cantonensis. It starts in a rodent and can reach slugs and snails. Eating uncooked snails is not the only thing that can lead these worms to infect the brain. Sometimes they leave residues on green leafy vegetables as well, from where their larvae can enter our bodies.
Creatures that feast on slugs and snails, such as crabs or prawns, can also lead to them entering our bodies. Consuming undercooked crabs or prawns is another way these worms can enter the body of a human being.
