DOI: 10.1038/s41467-022-34634-6 A study published in Nature Communications and directed by Professor Carlo Vittorio Cannistraci, Director of the Center for Complex Network Intelligence (CCNI) at the Tsinghua Laboratory of Brain and Intelligence, proposes a fast algorithm to measure the relation between the…

The research team found changes in the salience network in the brain of people exposed to trauma, including those with and without psychopathologies like PTSD, depression, and anxiety.Trauma can have a profound impact on an individual’s life. Recent research has shed light on how traumatic events can alter the physical structure of our brains. These changes are not due to physical injury but rather the brain’s ability to adapt and rewire itself after these experiences.The ZVR Lab at the Del Monte Institute for…

Brain health expert Marc Milstein has written about the diet of SuperAgers. Despite being in their 80s and beyond, some people have cognitive abilities…

Autism, also known as Autism Spectrum Disorder (ASD), is a complex developmental disorder that affects communication, social interaction, and behavior. It is characterized by difficulties in verbal and nonverbal communication, social interactions, and repetitive behaviors.A new study led by Rutgers University has highlighted the potential of innovative techniques in understanding and studying mental disorders.A new study led by scientists at Rutgers University has uncovered new insights into the underlying brain…

Scientists recently conducted an experiment using a mouse model that is susceptible to SARS-CoV-2 coronavirus infection. They found that the virus can infect various parts of the brain and cause brain damage. They also discovered that the CNB-CSIC vaccine effectively prevents the virus from infecting the brain.The study was conducted by Spanish researchers from the Institute of Biomedicine of Seville and published in the prestigious journal Nature Neuroscience.Although the main effects of <span…

Scientists have discovered a nerve pathway in mice that is involved in the processing of rewarding and distressing stimuli and situations. This pathway, called the median raphe nucleus, is located in the brain stem and acts in opposition to a previously identified pathway called the dorsal raphe nucleus. The discovery of this pathway could lead to the development of new drug treatments for mental disorders such as addiction and depression.New insights into the opposing actions of serotonin-producing nerve fibers in mice…

A team of researchers has identified the areas of the brain that enable us to solve problems without prior experience, also known as fluid intelligence. This type of intelligence is considered to be a key aspect of human cognition and is linked to a range of cognitive abilities, including memory, as well as educational and professional success, social mobility, health, and longevity. Fluid intelligence is involved in “active thinking,” which includes mental processes like abstraction, judgment, attention, strategy…

Sometimes what's good for your heart is also good for your brain.A recent study of US adults over 50 found that those who owned a pet for more than five years scored better on cognitive memory tests than those living without interspecies housemates.The findings from the University of Michigan suggest the 'pet effect' can protect more than just the health of our guts and hearts; it could also play a role in our aging brains.The results are based on a nationally representative survey from 2010 to 2016, which, amongst other…

Memory and perception seem like entirely distinct experiences, and neuroscientists used to be confident that the brain produced them differently, too. But in the 1990s, neuroimaging studies revealed that parts of the brain that were thought to be active only during sensory perception are also active during the recall of memories.“It started to raise the question of whether a memory representation is actually different from a perceptual representation at all,” said Sam Ling, an associate professor of neuroscience and…

Daily brain tests could reveal how prepared your immune system is to tackle a future viral infection.A study led by researchers at the University of Michigan (U-M) has shown that poor immune performance tends to go hand-in-hand with periods of fluctuating cognitive performance fluctuates.For the first few days of the eight day study, three times a day, 18 participants tested their attention, reaction time, and ability to switch between numbers and symbols. On the fourth day of the study, the group was purposefully…
