In fight against brain pathogens, the eyes have it      (via sciencedaily.com)     Original source 

The eyes have been called the window to the brain. It turns out they also serve as an immunological barrier that protects the organ from pathogens and even tumors, researchers have found. In a new study, researchers showed that vaccines injected into the eyes of mice can help disable the herpes virus, a major cause of brain encephalitis. To their surprise, the vaccine activates an immune response through lymphatic vessels along the optic nerve.

Addressing societal concerns of genetic determinism of human behavior by linking environmental influences and genetic research      (via sciencedaily.com)     Original source 

In a new perspective article, researchers underscore the importance of integrating environmental effects into genetic research. The authors discuss how failure to do so can perpetuate deterministic thinking in genetics, as historically observed in the justification of eugenics movements and, more recently, in cases of racially motivated violence.

New study links placental oxygen levels to fetal brain development      (via sciencedaily.com)     Original source 

A new study shows oxygenation levels in the placenta, formed during the last three months of fetal development, are an important predictor of cortical growth (development of the outermost layer of the brain or cerebral cortex) and is likely a predictor of childhood cognition and behavior.

Learning and memory problems in down syndrome linked to alterations in genome's 'dark matter'      (via sciencedaily.com)     Original source 

The activity of Snhg11, a gene found in the 'dark matter' of the genome, is critical for the function and formation of neurons in the hippocampus, specifically in an area critical for learning and memory. Researchers have discovered the gene is less active in brains with three copies of chromosome 21, which causes Down syndrome, potentially contributing to the condition's intellectual disabilities. The researchers plan on carrying out further research to discover the exact mechanisms of action involved, information that could open potential avenues for new therapeutic interventions.

Gut-brain communication turned on its axis      (via sciencedaily.com)     Original source 

The mechanisms by which antidepressants and other emotion-focused medications work could be reconsidered due to an important new breakthrough in the understanding of how the gut communicates with the brain. New research has uncovered major developments in understanding how the gut communicates with the brain, which could have a profound impact on the make-up and use of medications such as antidepressants.

Intervention reduces likelihood of developing postpartum anxiety and depression by more than 70%      (via sciencedaily.com)     Original source 

Results from a large clinical trial show that an intervention for anxiety provided to pregnant women living in Pakistan significantly reduced the likelihood of the women developing moderate-to-severe anxiety, depression, or both six weeks after birth.

Yoga provides unique cognitive benefits to older women at risk of Alzheimer's disease      (via sciencedaily.com)     Original source 

A new study found Kundalini yoga provided several benefits to cognition and memory for older women at risk of developing Alzheimer's disease including restoring neural pathways, preventing brain matter decline and reversing aging and inflammation-associated biomarkers -- improvements not seen in a group who received standard memory training exercises.

Revolutionary brain stimulation technique shows promise for treating brain disorders      (via sciencedaily.com)     Original source 

The human brain's adaptability to internal and external changes, known as neural plasticity, forms the foundation for understanding cognitive functions like memory and learning, as well as various neurological disorders. Scientists have now unveiled a novel technique that could transform the treatment landscape for brain disorders. The team developed a non-invasive brain stimulation method called Patterned Low-Intensity Low-Frequency Ultrasound (LILFUS), which holds tremendous potential for inducing long-lasting changes in brain function.

Hearing relaxing words in your sleep slows your heart down      (via sciencedaily.com)     Original source 

Researchers have investigated whether the body is truly disconnected from the external world during sleep. To do so, they focused on how heartbeat changes when we hear different words during sleep. They found that relaxing words slowed down cardiac activity as a reflection of deeper sleep and in comparison to neutral words that did not have such a slowing effect. This discovery sheds new light on brain-heart interactions during sleep.

Cracking the code of neurodegeneration: New model identifies potential therapeutic target      (via sciencedaily.com)     Original source 

Scientists have developed an innovative neural cell culture model, shedding light on the intricate mechanisms underlying neurodegeneration. Their research pinpointed a misbehaving protein as a promising therapeutic target in the treatment of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD).

Uncovering anxiety: Scientists identify causative pathway and potential cures      (via sciencedaily.com)     Original source 

Quick-acting targeted therapies with minimal side effects are an urgent need for the treatment of anxiety-related disorders. While delta opioid receptor (DOP) agonists have shown 'anxiolytic' or anxiety-reducing effects, their mechanism of action is not well-understood. A new study highlights the role of specific neuronal circuits in the brain involved in the development of anxiety, and distinct mechanisms of action of the therapeutic DOP agonist -- KNT-127.

Air pollution linked to more signs of Alzheimer's in brain      (via sciencedaily.com)     Original source 

People with higher exposure to traffic-related air pollution were more likely to have high amounts of amyloid plaques in their brains associated with Alzheimer's disease after death, according to a new study. Researchers looked at fine particulate matter, PM2.5, which consists of pollutant particles of less than 2.5 microns in diameter suspended in air.

Possible trigger for autoimmune diseases discovered : B cells teach T cells which targets must not be attacked      (via sciencedaily.com)     Original source 

Immune cells must learn not to attack the body itself. A team of researchers has discovered a previously unknown mechanism behind this: other immune cells, the B cells, contribute to the 'training' of the T cells in the thymus gland. If this process fails, autoimmune diseases can develop. The study confirms this for Neuromyelitis optica, a disease similar to Multiple Sclerosis. Other autoimmune diseases may be linked to the failure of this new mechanism as well.
