Researchers at the University of Valladolid are using EEG technology to make social media more accessible for individuals with physical disabilities. This research team created a computer system which can use an individual’s EEG signals to interpret and complete their desired action on social media.

By measuring their brain activity, researchers found that subjects who engaged with their memories at a moderate level were the most successful at forgetting them. They hope to use neurofeedback to help individuals dull traumatic memories by encouraging them to enter a moderately engaged brain state.

The human brain may be able to sense changes in the Earth’s magnetic field. In a recent study, the magnetic field in a sealed room was adjusted to mirror that of the Earth. When this occurred, many study participants had a spike in brain activity not seen when other types of magnetic fields were introduced.

Following extreme stress or trauma, some individuals experience a sudden swelling and weakening of their heart, a condition aptly named “broken-heart syndrome”. Sufferers have been found to have an underactive parasympathetic nervous system, which is meant to calm the body following stressful events.

After comparing the brain scans of children aged 9 to 11, investigators concluded that those who were involved in sports had a greater volume in their hippocampus. Interestingly, while this was associated with reduced depression in young boys, this association was not applicable in young girls.
