Compound Derived From Turmeric Essential Oil Has Neuroprotective Properties

Summary: Aromatic turmerone, a compound derived from turmeric essential oil, and its derivatives directly affect dopamine neurons to generate neuroprotective properties in tissue culture models of Parkinson’s disease.

Researchers from Kumamoto University, Japan have found that a component derived from turmeric essential oil, aromatic turmerone (ar-turmerone), and its derivatives act directly on dopaminergic nerves to create a neuroprotective effect on tissue cultures of a Parkinson’s disease model.

Mini-Brain Study Shows How Environmental Risk Factors Can Amplify Genetic Risks for Autism

Summary: Using human stem cells to develop a brain organoid model, researchers were able to show exposure to a common pesticide synergizes with an autism-linked gene mutation. The study provides clear evidence that genetics and environment may combine to disrupt neurodevelopment.

Researchers at Johns Hopkins Bloomberg School of Public Health have shown in a brain organoid study that exposure to a common pesticide synergizes with a frequent autism-linked gene mutation.

Device taps brain waves to help paralyzed man communicate

In a medical first, researchers harnessed the brain waves of a paralyzed man unable to speak — and turned what he intended to say into sentences on a computer screen.

It will take years of additional research but the study, reported Wednesday, marks an important step toward one day restoring more natural communication for people who can’t talk because of injury or illness.

“Most of us take for granted how easily we communicate through speech,” said Dr. Edward Chang, a neurosurgeon at the University of California, San Francisco, who led the work. “It’s exciting to think we’re at the very beginning of a new chapter, a new field” to ease the devastation of patients who lost that ability.

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

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.

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

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.
