A team of researchers led by Rice University’s Jacob Robinson and the University of Texas Medical Branch’s Peter Kan has developed a technique for diagnosing, managing and treating neurological disorders with minimal surgical risks. The team’s findings were published in Nature Biomedical Engineering.

While traditional approaches for interfacing with the nervous system often require creating a hole in the skull to interface with the brain, the researchers have developed an innovative method known as endocisternal interfaces (ECI), allowing for electrical recording and stimulation of neural structures, including the brain and spinal cord, through cerebral spinal fluid (CSF).

“Using ECI, we can access multiple brain and spinal cord structures simultaneously without ever opening up the skull, reducing the risk of complications associated with traditional surgical techniques,” said Robinson, professor of electrical and computer engineering and bioengineering.

A new frequency-based analysis of recordings from neurons in the brain may give insight into brain pathologies such as Parkinson’s disease.

Summary: A recent study offers new insights into how brain regions coordinate during rest, using resting-state fMRI (rsfMRI) and neural recordings in mice. By comparing blood flow patterns with direct neural activity, researchers found that some brain activity remains “invisible” in traditional rsfMRI scans. This hidden activity suggests that current brain imaging techniques may miss key elements of neural behavior.

The findings, potentially applicable to human studies, may refine our understanding of brain networks. Further research could improve the accuracy of interpreting brain activity.

This study explores how muscle contractions, such as those that occur during exercise, influence motor neurons—the cells responsible for controlling muscle movement.

There’s no doubt that exercise does a body good. Regular activity not only strengthens muscles but can bolster our bones, blood vessels, and immune system.

Now, MIT engineers have found that exercise can also have benefits at the level of individual neurons. They observed that when muscles contract during exercise, they release a soup of biochemical signals called myokines.

A new computational method can identify how cause-and-effect relationships ebb and flow over time in dynamic real-life systems such as the brain.

Male and female mice use different brain circuits to process threats, revealing sex-specific neural pathways despite similar behaviors. These findings suggest the need for sex-inclusive neuroscience research to improve understanding and treatments.

Adverse childhood experiences can lead to adult symptoms of anxiety and depression, mediated by life history strategies, according to a study published in Biodemography & Social Biology.

Existing research underscores the psychological impact of early-life adversity, with theories across cognitive, behavioral, and evolutionary psychology exploring these long-term effects. The life history theory, specifically, offers insight by framing adverse childhood experiences (ACEs) in terms of fast or slow life strategies, each with distinct reproductive and developmental adaptations suited to one’s environment.

YouTube videos on autism primarily provide educational content with balanced perspectives, reducing stigmatization, though viewer comments often remain negative. This highlights YouTube’s dual role in improving understanding while revealing persistent public misconceptions.

Substance use disorders are a group of conditions involving the recurrent use of substances, like drugs or alcohol, despite harmful consequences to physical, mental, or social health. These disorders are characterized by an inability to control usage, intense cravings, and continued use despite negative impacts on relationships, work, or health.

While it is well-known that substance use disorders have negative consequences for the individual, research has recently begun to focus on the effects of these disorders on others, known as the “harm to others” framework. A key area of these studies is the impact on children growing up with parents affected by substance use disorders. These children have been found to have lower academic achievement than their peers whose parents do not have such disorders, as well as an increased risk of various mental health and developmental issues.

Study author Hélio Manhica and his colleagues aimed to explore the mental health risks for children of parents with substance use disorders in greater detail. They also sought to determine whether these risks differ between males and females and if certain periods in childhood or adolescence are particularly critical in relation to exposure to parental substance use disorder (i.e., periods that influence the overall risk of developing psychiatric disorders).
