Our state of attention is shaped by a handful of neurons
A team from the University of Geneva and ETH Zurich has shown how the locus coeruleus, a small region of the brain, manages the transition from intense focus to heightened global awareness. What enables our brain to go from intense concentration to a heightened state of alertness? A study carried out by neuroscientists at the University of Geneva , in collaboration with ETH Zurich, shows that a brain region called locus coeruleus (LC) and the neurotransmitter noradrenaline act as conductors, reorganising brain functions according to the mental demands of the moment.

Insulin cells don’t need to team up
Our glycaemic balance is based on the ability of the pancreatic beta cells to detect glucose and secrete insulin to maintain our blood sugar levels. If these cells malfunction, the balance is broken, and diabetes develops. Until now, the scientific community agreed that beta cells needed the other hormone-producing cells of the pancreas to function properly.
