by Children’s Hospital Boston This image shows how insufficient sleep, frequent difficulty falling asleep at night, and increased frequency of snoring affect regional networks in the brain. These effects are distributed throughout the brain, including regions (such as frontal cortical areas) that are still developing in early adolescence and support high-level cognitive processes.

by Bob Yirka , Medical Xpress Credit: CC0 Public Domain A team of researchers at Zhejiang University in China has found evidence suggesting that the brain blocks retention of some memories even when a person actively attempts to remember them. In their paper published in the journal Science Advances, the group describes multiple experiments they conducted...
by University of Turku Impact of obesity risk factors on brain function. a) Family-related risk factors (parents’ obesity and diabetes) were associated with altered insulin signalling in the subject’s widespread brain regions. More yellow colour signifies stronger association. b) Family-related risk factors were associated with decreased opioid receptor availability in regions related to producing pleasure...
by Erica K. Brockmeier, University of Pennsylvania Vijay Balasubramanian. Credit: University of Pennsylvania A study published in PLOS Computational Biology describes a new model for how the olfactory system discerns unique odors. Researchers from the University of Pennsylvania found that a simplified, statistics-based model can explain how individual odors can be perceived as more or less similar from...
by Georg Meisl, The Conversation Credit: Yurchanka Siarhei/Shutterstock Alzheimer’s disease and other types of dementia affect more than 55 million people worldwide. But the development of effective treatments and cures is progressing slowly. To some extent, this is because we still don’t understand enough about what causes the disease and drives its progression. Myself and my...
by University of Cambridge Credit: Pixabay/CC0 Public Domain For the first time, researchers have used human data to quantify the speed of different processes that lead to Alzheimer’s disease and found that it develops in a very different way than previously thought. Their results could have important implications for the development of potential treatments. The...
The human brain is the most effective known processing unit. It constantly receives and processes numerous signals from both the outside world and our interior. Every day countless processes going on in it, even while we are asleep, engaging 200 billion neurons in complex signal transmission. All these neurons are joined with an incredible number of connections....

Megan Brooks October 06, 2021 Psychological therapy that changes an individual’s beliefs about pain not only provides lasting chronic pain relief but also alters brain regions related to pain generation, new research shows. In the first randomized controlled test of pain reprocessing therapy (PRT), two thirds of patients with chronic back pain (CBP) who received 4 weeks...
