Online gaming addiction in men affects brain’s impulse control

Researchers using functional MRI (fMRI) have found differences in the brains of men and women who are addicted to online gaming, according to a new study.

Advanced imaging technology measures magnetite levels in the living brain

Investigators have used magnetoencephalography — a technology that measures brain activity by detecting the weak magnetic fields produced by the brain’s normal electrical currents — to measure levels of the iron-based mineral called magnetite in the …

Beware of evening stress

Stressful events in the evening release less of the body’s stress hormones than those that happen in the morning, suggesting possible vulnerability to stress in the evening.
