A virtual reality world called EVA Park can improve the communication of those who have impaired speech and language following a stroke, according to research by academics at City University London. The study, which is published in PLOS ONE, is the first exploration of multi-user virtual reality in aphasia therapy and shows the potential for technology to play an important role in improving the everyday lives of people with the condition.

A new study will look at how brain connections mature and develop from childhood to adulthood.

Neurons communicate by sending chemical signals called neurotransmitters across synapses, specialized connections between two individual cells. This communication requires a delicate and intricate molecular architecture. A recent paper published in Nature has now shown that the structure of this intercellular space is more complicated than previously thought, and it probably helps boost the efficiency of the signaling.

A new long term study of young marijuana users tracks the brain’s response to reward over time. The findings indicate a lower response to reward in marijuana users.

Neuroscientists at the University of Pittsburgh have identified the neural networks that connect the cerebral cortex to the adrenal medulla, which is responsible for the body’s rapid response in stressful situations. These findings, reported in the online Early Edition of the journal Proceedings of the National Academy of Sciences (PNAS), provide evidence for the neural basis of a mind-body connection.

A new study provides insight into how overconfidence can lead to poor decision making.

Scientists have identified part of our brain that helps us learn to be good to other people. The discovery could help understanding of conditions like psychopathy where people’s behaviour is extremely antisocial.

Finally this week, researchers have developed a neurodevelopmental model of a rare genetic disorder that could help shed light on the workings of the human social brain.
