Scientists have discovered that older honey bees effectively reverse brain aging when they take on nest responsibilities typically handled by much younger bees. While current research on human age-related dementia focuses on potential new drug treatments, researchers say these findings suggest that social interventions may be used to slow or treat age-related dementia.

Although many areas of the human brain are devoted to social tasks like detecting another person nearby, a new study has found that one small region carries information only for decisions during social interactions. Specifically, the area is active when we encounter a worthy opponent and decide whether to deceive them.

Scientists tracked brain activity in 40 people with new back injuries and found a pattern of activity that could predict — with 85% accuracy — which patients were destined to develop chronic pain and which weren’t.

Scientists have discovered a mechanism which stops the process of forgetting anxiety after a stress event. In experiments they showed that feelings of anxiety don’t subside if too little dynorphin is released into the brain. The results can help open up new paths in the treatment of trauma patients.

Research published in Neuron reveals that underdevelopment of an impulse control center in the brain is, at least in part, the reason children who fully understand the concept of fairness fail to act accordingly.

Researchers are developing a robotic system with ability to predict the specific action or movement that they should perform when handling an object.

The widely used diabetes drug metformin comes with a rather unexpected and  side effect: it encourages the growth of new neurons in the brain.

Researchers have long been interested in discovering the ways that human brains represent thoughts through a complex interplay of electrical signals. Recent improvements in brain recording and statistical methods have given researchers unprecedented insight into the physical processes under-lying thoughts. For example, researchers have begun to show that it is possible to use brain recordings to reconstruct aspects of an image or movie clip someone is viewing, a sound someone is hearing or even the text someone is reading.

A new brain scanner has been developed to help people who are completely paralysed speak by enabling them to spell words using their thoughts.
