Species of Gut Bacteria Linked to Enhanced Cognition and Language Skills in Infant Boys

Posted by in category: neuroscience

Summary: Infant boys with a gut bacterial composition high in Bacteroidetes were found to have more advanced cognitive and language skills one year later compared to boys with lower levels of the bacteria.

Source: University of Alberta.

The University of Alberta-led research followed more than 400 infants from the CHILD Cohort Study (CHILD) at its Edmonton site. Boys with a gut bacterial composition that was high in the bacteria Bacteroidetes at one year of age were found to have more advanced cognition and language skills one year later. The finding was specific to male children.

Neuroscientists assess the impact of a short-term musical training on implicit emotion regulation

Posted by in categories: biotech/medical, media & arts, neuroscience

Emotion regulation is an essential aspect of mental health and wellbeing. In fact, past studies have found associations between poor emotion regulation and several psychiatric disorders, including bipolar disorder, borderline personality disorder and complex post-traumatic stress disorder (PTSD).

During their everyday life, humans can regulate their negative emotions in different ways, most of which do not require any conscious cognitive engagement. For instance, they might take a bath, step outside for fresh air or listen to .

Researchers at Radboud University Nijmegen in The Netherlands, the Norwegian University of Science and Technology (NTNU), and University Hospital Aachen, Germany have recently carried out a study aimed at investigating the effects of a short-term on implicit emotion regulation. Their paper, published in BMC Neuroscience, specifically examined whether musical training helped people to reduce the negative emotions elicited by unpleasant or disgusting odors.

When Neurogenesis Encounters Aging and Disease

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

Circa 2010


In this review, we consider the evidence that a reduction in neurogenesis underlies aging-related cognitive deficits, and impairments in disorders such as Alzheimer’s disease (AD). The molecular and cellular alterations associated with impaired neurogenesis in the aging brain are discussed. Dysfunction of presenilin-1, misprocessing of amyloid precursor protein and toxic effects of hyperphosphorylated tau and β-amyloid likely contribute to impaired neurogenesis in AD. Since factors such as exercise, enrichment and dietary energy restriction enhance neurogenesis, and protect against age-related cognitive decline and AD, knowledge of the underlying neurogenic signaling pathways could lead to novel therapeutic strategies for preserving brain function. In addition, manipulation of endogenous neural stem cells and stem cell transplantation, as stand-alone or adjunct treatments, seem promising.

There is a progressive decline in the regenerative capacity of most organs with increasing age, resulting in functional decline and poor repair from injury and disease. Once thought to exist only in high turnover tissues, such as the intestinal lining or bone marrow, it now appears that most tissues harbor stem cells that contribute to tissue integrity throughout life. In many cases, stem cell numbers decrease with age, suggesting stem cell aging may be of fundamental importance to the biology of aging (for review, see Ref. [1]). Therefore, understanding the regulation of stem cell maintenance and/or activation is of considerable relevance to understanding the age-related decline in maintaining tissue integrity, function, and regenerative response.

Brain fog and rheumatoid arthritis: What is the link?

Posted by in categories: biotech/medical, neuroscience

Many people with rheumatoid arthritis, or RA, report having trouble thinking clearly, problems with memory, and difficulty concentrating.

These symptoms, known as brain fog, are widespread in people with chronic inflammatory conditions, including RA, Sjogren’s syndrome, and multiple sclerosis.

Memory Making Involves Extensive DNA Breaking

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

If you want to learn, then you have to break some things.


Summary: Brain cells snap DNA in more places and in more cell types than previously realized in order to express genes for learning and memory.

Cell Structure Previously Associated With Disease Actually Improves Brain Function

Posted by in categories: biotech/medical, neuroscience

Summary: Axonal swelling in the Purkinje cells of mice had no detrimental impact on firing rate or the speed at which axons transmit signals. At peak firing rate, axons with swellings were less likely to fail than those without.

Source: McGill University.

Researchers at McGill University have shown that a brain cell structure previously thought to be pathological in fact enhances cells’ ability to transmit information and correlates with better learning on certain tasks.

Rise of the cyborgs: Inside the technology transcending humanity’s biological limits

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

Humans are integrating with technology. Not in the future – now. With the emergence of custom prosthetics that make us stronger and faster, neural implants that change how our brains work, and new senses and abilities that you’ve never dreamed of having, it’s time to start imagining what a better version of you might look like.


From reality-enhancing implants to brain-controlled exoskeletons, breakthroughs in bio-tech have fuelled a new fusion of machinery and organic matter.

‘Superager’ Brains Resist The March of Time to Have Memories Like 25-Year-Olds

Posted by in category: neuroscience

A rare group of humans known as “superagers” can grow up without their minds growing old.

Even in their 60s, 70s, and 80s, a lucky few maintain incredibly youthful memories, recalling new experiences, events, and situations just as well as people decades younger.

New research now suggests that’s because their brains have somehow resisted the march of time.
