Researchers say those who use both cannabis and nicotine have greater brain connectivity that those who take one or the other. The networks of those who used both substances closely resembled those who people who took neither drug.
According to a new study published in the Journal of Abnormal Psychology, the brains of women with the eating disorder Bulimia Nervosa respond differently to images of sugary and high-fat foods following a stressful situation than those without the disorder. Brain scans reveal bulimic women have decreased blood flow to the precuneus, an area of the brain associated with self-criticism, when presented with images of food following a stressful math test. The findings provide support to current theories that binge eating may provide an alternative focus to negative self-reflections.
Using the movie Memento, researchers discover how the brain creates memories to piece together complex story lines.
Researchers reveal the precuneus is more connected to the dorsal attention network and less connected to the default mode network in people with chronic tinnitus.
Shorter sleep duration can increase the risk of children developing depression, anxiety, and cognitive problems. Children who routinely suffered sleep disruptions or shorter sleep durations had reduced brain volume in the orbitofrontal cortex, prefrontal cortex, precuneus, supramarginal gyrus, and temporal cortex.
A new study sheds light on how highly sensitive people process information. After experiencing something emotionally evocative, brain activity displayed a depth of processing while at rest. Depth of processing is a key feature of high emotional sensitivity.
Researchers focus on gray matter volume on three areas of the brain. Findings suggest cardiovascular risk factors such as obesity and diabetes could be early indicators for Alzheimer's disease.
