Scientists link baby’s brain development to their gut bacteria

Posted by in categories: biotech/medical, neuroscience

The development of your baby’s brain could be influenced by the microbes in their belly, scientists have found.

The trillions of microbes that live inside our guts play essential roles in a range of bodily processes, from digestion to mental health. The gut contains more than 100 million nerve cells—the highest concentration in any part of the body other than the brain. Now, we are also beginning to learn about the roles of these microbes in the earliest stages of our lives.

“The microbiome plays an important role in the early development of several systems, such as the nervous and immune system, as well as providing another layer of protection against pathogens [disease],” Sebastian Hunter, a researcher from the University of British Columbia who led a study on the subject published Wednesday in the scientific journal PLOS One, told Newsweek.

Most Brain Aneurysms Don’t Cause Symptoms

Posted by in categories: biotech/medical, neuroscience

You could be walking around with an unruptured brain aneurysm. But don’t panic – the Brain Aneurysm Foundation estimates that about 1 in 50 people in the U.S. has an unruptured brain aneurysm. Director of Endovascular Neurosurgery Koji Ebersole, MD, says people are surprised to learn that the majority of aneurysms don’t cause any symptoms.

An aneurysm develops when a vessel in the brain has a thin spot, which then fills with blood, creating a bulge or balloon shape. Most brain aneurysms are small, about the size of a pea. Because the brain itself has no sensory fibers, there is no pain and the brain doesn’t register that the aneurysm is there.

“Most patients find out they have an aneurysm for a completely unrelated reason,” Dr. Ebersole says. “Maybe they’re having trouble with their sinuses and have a CT scan and the doctors find an aneurysm. When you learn you have an aneurysm, it’s important to meet with a physician who’s practiced in neurology to talk about the implications.”

Gastrointestinal Syndromes May Predict Parkinson’s Disease, Study Suggests

Posted by in categories: biotech/medical, neuroscience

A recent study published in BMJ Gut conducted using a nationwide medical record network in the United States has shed light on potential links between gastrointestinal (GI) syndromes and the development of Parkinson’s disease (PD). Researchers led by Bo Konings aimed to determine whether specific GI conditions and interventions precede the onset of PD when compared with negative controls, Alzheimer’s disease (AD), and cerebrovascular diseases (CVD).

Here are the key findings from the study:

● PD-Specific Associations: The study identified several GI conditions that exhibited specific associations with PD in both case-control and cohort analyses. These conditions included gastroparesis, dysphagia, irritable bowel syndrome (IBS) without diarrhoea, and constipation.

Alzheimer’s: Exercise-induced hormone may help reduce plaque

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

He added the study may lead doctors to try finding medications to mimic the effect of exercise without actually requiring physical activity.

“While this research shows promising results, a lot more research would be needed to show how much of an impact it would make on people with Alzheimer’s and how much would be needed for a preventive effect,” Voci said. “But I would argue that this gives more evidence to the broad spectrum of what exercise can treat. Exercise is medicine.”

Lucid dreamers transmit musical melodies from dreams to reality in real-time in groundbreaking study

Posted by in categories: electronics, neuroscience

Researchers from the California-based startup REMspace successfully transferred melodies from lucid dreams to reality using electronic sensors and specialized software. The study, which recorded melodies dreamt during lucid dreams via electromyography (EMG), opens possibilities for musicians to capture and share unique compositions directly from their dreams…

Specialized astrocyte subpopulation discovery sheds light on brain health and treatment avenues

Posted by in categories: health, neuroscience

In a recent study published in Nature, researchers investigated whether glutamatergic gliotransmission was mediated by specialized astrocytes in the central nervous system.

The role of astrocytes in brain circuitry function, such as swift glutamate release, has been questioned due to inconsistent data and lack of direct evidence. This mechanism, similar to neurons, controls plasticity, excitability, and coordinated activity of synaptic-type networks but also contributes to neuropsychiatric conditions.

Could your gut microbiome shape your teenage years? New study dives into the lifelong health impact

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

Research explores how the gut microbiota impacts critical areas of adolescent development, including mental health, metabolism, and skeletal growth. It suggests that understanding these interactions could lead to microbiome-based treatments for optimal growth and maturation.

Scientists use video games to measure the eye-brain-body connection

Posted by in categories: biotech/medical, entertainment, food, health, neuroscience

Video games could give ophthalmologists an easy window not into the soul, but into eye health and the eye-brain-body connection — the three-way reciprocal communication that influences our actions.

“Infusing science into games is like sneaking broccoli into ice cream,” said Khizer Khaderi, MD, a clinical associate professor of ophthalmology. “It removes the resistance to do something that may not be viewed as fun, such as eating vegetables.” Or in this case, evaluating your vision health.

In a Stanford Medicine-led study, researchers employed video games to evaluate participants’ field of vision and visual stamina, their ability to distinguish contrast, and other factors that can indicate common eye diseases.
