Although it is known that sleep improves cognitive performance, the underlying neural mechanisms, especially in the context of non-REM sleep, are still largely unexplored. A new study by a team of researchers from Rice University and Houston Methodist’s Center for Neural Systems Restoration and Weill Cornell Medical College, coordinated by Valentin Dragoi of Rice University, […]
Anxiety and Depression: The Role of the Amygdala
Treatment for anxiety, depression and other disorders may depend on the amygdala, a part of the brain that controls strong emotional responses, particularly fear. Until now, however, there has been a lack of in-depth understanding of this structure. Now, scientists at the University of California, Davis, have identified new cell clusters with distinct gene expression […]
Is Poor Sleep Quality in Childhood Associated With a Higher Risk of Drug Use and Mental Disorders?
Getting enough sleep is especially important for children, as it promotes growth and development. Children who suffer from chronic sleep deprivation from an early age may be more likely to suffer health problems and may even be at increased risk of developing psychosis in early adulthood, new research shows. Researchers at the University of Birmingham […]
New High-Resolution 3D Maps Show How the Brain’s Blood Vessels Change With Age
Healthy blood vessels are not only important for heart health. Vascular well-being is critical for brain health and potentially for combating age-related cognitive decline and neurodegenerative diseases such as Alzheimer’s disease, according to a new study led by Penn State researchers. The findings point to a previously understudied but potentially crucial role that the brain’s […]
Inflammation in Young Adulthood Has an Impact on Mental Health
Higher levels of inflammation in young adulthood are linked to lower performance on skills tests in midlife. Young adults with elevated levels of inflammation associated with obesity, physical inactivity, chronic disease, stress and smoking may have lower cognitive performance in midlife, a new UC San Francisco study shows. Researchers had previously linked higher levels of […]
