High doses of ketamine can temporarily switch off the brain

Researchers have identified two brain phenomena that may explain some of the side-effects of ketamine. Their measurements of the brain waves of sheep sedated by the drug may explain the out-of-body experience and state of complete oblivion it can cause.

What can maritime shipping learn from brain network science?

Researchers show how network science computational theories used for brain analysis can help us to understand global shipping networks and their impact on the world economy.

Noise disturbs the brain’s compass

Our sense of direction tends to decline with age. Researchers report on new insights into the causes of this phenomenon. These study results could contribute to the development of diagnostic tools for early detection of dementia.
