Most people know that listening to loud sounds will temporarily disrupt their hearing. Swedish researchers can now tell us how that happens — they identified the specific part of the hearing organ affected by sounds. “We have discovered that a tiny structure in the cochlea known as the tectorial membrane plays an important role in this […]

Empathy is NOT unique to humans: Researchers discover that rats feel the pain of others, too
Rats share some behavioral traits with humans. Now, a new Dutch study claims that the animals also empathize with others and share their pain. When a person experiences physical pain, the cingulate cortex of the brain activates in response. This region also displays activity when the person sees another individual getting hurt. Researchers at the […]

Working out in the morning helps improve cognitive function throughout the day, say researchers
A recent study from Australia found that morning workouts can greatly improve working memory in older adults. In the paper, which was published in The British Journal of Sports Medicine, the researchers discussed whether moderate-intensity exercises can improve cognition in older adults and whether adding light-intensity walking breaks can further their brain-boosting effects. A collaboration between […]

Flashing lights and pink noise could be the key to preventing Alzheimer’s
Researchers believe they have found a potential treatment for Alzheimer’s disease. Animal tests show that exposing mice to light flashes and sound pulses at the frequency of 40 hertz can reverse some of the symptoms of the neurodegenerative disease. Alzheimer’s disease continues to defy any attempt at treating it. Several pharmaceutical drugs help regulate a few […]

Researchers use electrical stimulation to improve depression symptoms
Patients with depression may experience improvements in their symptoms if they tried a new electricity-based stimulation therapy. Developed by North Carolina-based researchers, the transcranial alternating current stimulation (tACS) treatment applies gentle electrical stimulation to the scalp to adjust the recipient’s natural alpha brainwaves. In a recent study, researchers from the University of North Carolina at Chapel Hill placed […]

The science of linguistics: The brain processes concrete vs. abstract words differently
In an review published in the Journal of Neurophysiology, an Italian researcher explored the various areas of the human brain responsible for processing the meanings of concrete and abstract words. Language is generally separated into two categories, concrete and abstract. Concrete words refer to things that exist in the physical world and can be perceived by the five senses. […]

The mechanics of why exercise is good for brain health, memory
An international study presented further evidence that irisin protects neurons in the brain from degeneration. It showed that the so-called “exercise-induced hormone” can improve memory in humans and mice. First identified in 2012 by researchers from the Harvard Medical School, irisin is a messenger hormone that helps convert white fat into brown fat, which produces heat. It was named […]

Fighting your cravings: Researchers identify new brain circuits that can help curb junk food cravings
There is a neural circuit in the brain that regulates the craving for more food. Researchers from The University of Texas Medical Branch (UTMB) identified it as the neuromedin U receptor 2. When they blocked this receptor in the brain of rats, the animals stopped craving junk food. “When trying to lose weight people often strive to avoid fatty […]
