Camacho et al. show that emotion concepts are represented throughout the brain, giving insight to how the brain perceives real-world emotions. These patterns are present before children enter school and become more standardized across adolescence.

BRISBANE, Australia — COVID-19 infections have a lengthy track record of impacting both neurological health and thinking abilities. Some patients experience brain inflammation, while others are…

Conversations About AI: Using it to transform the treatment of mental health and for the promotion of social good.

How can AI be used to help human mental health and address the social good? Aryan Pandey, a new guest contributor shows us.

Have you ever made a great catch—like saving a phone from dropping into a toilet or catching an indoor cat from running outside? Those skills—the ability to grab a moving object—takes precise interactions within and between our visual and motor systems. Researchers at the Del Monte Institute for Neuroscience at the University of Rochester have found that the ability to visually predict movement may be an important part of the ability to make a great catch—or grab a moving object.

“We were able to develop a method that allowed us to analyze behaviors in a natural environment with high precision, which is important because, as we showed, behavioral patterns differ in a controlled setting,” said Kuan Hong Wang, Ph.D., a Dean’s Professor of Neuroscience at the University of Rochester Medical Center.

Wang led the study out today in Current Biology in collaboration with Jude Mitchell, Ph.D., assistant professor of Brain and Cognitive Sciences at the University of Rochester, and Luke Shaw, a graduate student in the Neuroscience Graduate Program at the School of Medicine & Dentistry at the University of Rochester. “Understanding how natural behaviors work will give us better insight into what is going awry in an array of neurological disorders.”

BOCA RATON, Fla. (AP) — Before Fred Kalfon began exercising at the Grey Team veterans center a couple months ago, the 81-year-old rarely left his Florida home.

Parkinson’s disease, an inner ear disorder and other neurological problems, all likely caused by the Vietnam vet’s exposure to the infamous defoliant Agent Orange, made it difficult for him to move. His post-traumatic stress disorder, centering on the execution of a woman who helped his platoon, was at its worst.

Switching to a diet full of fresh veggies and low in processed foods could do wonders for your brain’s biological age, new research shows.

According to the international team of researchers who ran the study, eating a Mediterranean diet rich in vegetables, seafood, and whole grains appears to slow the signs of accelerated brain aging typically seen in obesity with as little as 1 percent loss in body weight.

Brain scans taken after 18 months showed the participants’ brain age appearing almost 9 months younger than expected, compared to estimates of their brain’s chronological age.

The ability of the phenomenon of criticality to explain the sudden emergence of new properties in complex systems has fascinated scientists in recent decades. When systems are balanced at their “critical point,” small changes in individual units can trigger outsized events, just as falling pebbles can start an avalanche. That abrupt shift in behavior describes the phase changes of water from ice to liquid to gas, but it’s also relevant to many other situations, from flocks of starlings on the wing to stock market crashes. In the 1990s, the physicist Per Bak and other scientists suggested that the brain might be operating near its own critical point. Ever since then, neuroscientists have been searching for evidence of fractal patterns and power laws at work in the brain’s networks of neurons. What was once a fringe theory has begun to attract more mainstream attention, with researchers now hunting for mechanisms capable of tuning brains toward criticality.

Northwestern Medicine investigators have developed a novel nanoparticle treatment for glioblastoma, according to a study published in Nature Communications.

Glioblastoma, the most common type of primary brain cancer, is one of the most complex, deadly and treatment-resistant cancers, according to the National Brain Tumor Society. The five-year survival rate for glioblastoma patients hovers near 7% and has remained unchanged for decades.

Previous Northwestern Medicine research has shown that glioblastoma tumors accumulate large numbers of immunosuppressive tumor-associated myeloid cells (TAMCs), which impairs the immune system’s ability to fight the tumor and reduces the effectiveness of radiation and chemotherapy.

Why does all of this matter? The unfortunate truth is that each of us will experience plenty of mental pain, misery, and frustration in our lifetimes. Mistaking the voice in our head for a thing and labeling it “me” brings us into conflict with the neuropsychological evidence that shows there is no such thing. This mistake — this illusory sense of self — is the primary cause of our mental suffering. When you can’t sleep at night, is it because you are worried about a stranger’s problems, or is it your problems that keep you up? For most of us, we worry about my work problems, my money problems, and my relationship problems. What would happen if we removed the “self” from these problems?

I am distinguishing mental suffering from physical pain. Pain occurs in the body and is a physical reaction—like when you stub your toe or break an arm. The suffering I speak of occurs in the mind only and describes things such as worry, anger, anxiety, regret, jealousy, shame, and a host of other negative mental states. I know it’s a big claim to say that all these kinds of suffering are the result of a fictitious sense of self. For now, the essence of this idea is captured brilliantly by Taoist philosopher and author Wei Wu Wei when he writes, “Why are you unhappy? Because 99.9 percent of everything you think, and of everything you do, is for yourself — and there isn’t one.”
