New research suggests that the brain of a bilingual person who knows two alphabets is different from that of a bilingual person who only knows one alphabet. The differences occur in a region called the visual word form area (VWFA).

A new study reports chronic infections of the upper gastrointestinal tract could be linked to Parkinson’s disease. Researchers say alpha synuclein, a Parkinson’s linked protein, is released during upper GI infections, inducing an immune response. Findings suggest frequent chronic infections could overwhelm the body’s ability to remove the protein, leading to the onset of Parkinson’s.

New research has found significant changes in fathers’ brains between the prenatal and the postpartum period. The main changes occurred in cortical areas associated with visual processing, attention, and empathy toward their baby.

A novel deep learning method that uses graph convolutional neural networks (gCNNs) can predict cognitive function based on the brain’s size and structure. The algorithm may provide insights into the relationship between brain morphology and different cognitive functions, as well as declines in cognitive function.

A study led by researchers at the Hospital del Mar Medical Research Institute links psychological trauma in childhood with an increased risk of developing some kind of mental disorder years later.

Music can induce a range of emotions and help us to better understand different cultures. But what is it that makes us tune in to some songs more than others? Researchers say when we listen to a song, our brains predict what happens next, and that prediction dictates whether we like that song or not.

Finally this week, a new study published by University of Oxford researchers in JMIR Pediatrics and Parenting, shows that although many school-age adolescents are spending considerable time gaming, it is not having a negative impact on their well-being.

People who are better able to move to a beat show more consistent brain responses to speech than those with less rhythm, according to a study published in the September 18 issue of The Journal of Neuroscience. The findings suggest that musical training could possibly sharpen the brain’s response to language.

Concussions are connected with substance abuse and suicidal thoughts in adolescents, according to new research presented at a conference on sports-related brain injuries.

The structure of the brain may predict whether a person will suffer chronic low back pain, according to researchers who used brain scans. The results, published in the journal Pain, support the growing idea that the brain plays a critical role in chronic pain, a concept that may lead to changes in the way doctors treat patients.

A drug commonly used for treating diabetes may reverse symptoms of late-stage Alzheimer’s disease and is now in the process of entering a major clinical trial.

Scientists have found a new link between early-onset Parkinson’s disease and a piece of DNA missing from chromosome 22. The findings help shed new light on the molecular changes that lead to Parkinson’s disease.

The pain and itching associated with shingles and herpes may be due to the virus causing a “short circuit” in the nerve cells that reach the skin, researchers have found.

In a new study looking at toddlers and preschoolers with autism, researchers have found that children with better motor skills were more adept at socializing and communicating. This study adds to growing evidence of the important link between autism and motor skill deficits. Motor skills and muscle memory are held in the cerebellum.

Scientists have discovered differences in the brain structure of ballet dancers that may help them avoid feeling dizzy when they perform pirouettes.

New research could offer solutions into slowing down the progression of motor neurone disease (MND).

Playing first person action games can enhance your perception of movement – but only when you’re walking backwards. This is one of the findings of a new paper by University of Leicester psychologists, published in the journal Perception, which examines the effect of playing video games on motion perception.

Two new studies investigate the relationship between self-control and reward processing for chronic dieters and people who would like to control their food intake.

Scientists say they have discovered the specific brain circuitry that causes overeating, according to a study published in the journal Science.

Bad experiences enhance memory formation about places, scientists at The University of Queensland have found.

Finally this week, a new study from MIT reveals a gene that is critical to the process of memory extinction. Enhancing the activity of this gene, known as Tet1, might benefit people with posttraumatic stress disorder (PTSD) by making it easier to replace fearful memories with more positive associations,

The Guardian newspaper reports on a new study on how video games can persist in our perception as fleeting hallucinations in an effect labelled ‘game transfer phenomena’.

Responding to faces is a critical tool for social interactions between humans. Without the ability to read faces and their expressions, it would be hard to tell friends from strangers upon first glance, let alone a sad person from a happy one. Now, neuroscientists from the California Institute of Technology (Caltech), with the help of collaborators at Huntington Memorial Hospital and Cedars-Sinai Medical Center, have discovered a novel response to human faces by looking at recordings from brain cells in neurosurgical patients.

New medical research tends to confirm that the human brain does not stop developing in adolescence, but continues well into our 20s, according to investigators at the University of Alberta.

A review of the evidence to date suggests that music therapy can help patients recover their movements after experiencing brain damage.

Frontotemporal dementia—triggered by cell death in the front and sides of the brain—accounts for about one-fourth of all cases of early-onset dementia. Now, scientists at UCLA have discovered that a certain signaling pathway plays a key role in the brain disorder and may offer a potential target for treatment.

Finally, the latest research shows that your learning can continue even while you sleep, so those adverts for products that help you learn while you sleep may be true after all!
