Researchers at the University of Northumbria are seeking volunteers for two studies, who’ll each be paid as much as £65, to investigate the benefits of red wine on brain function.

Volunteers must be non-smokers aged between either 18-35 or 50-70, and in good health. They’ll be required to attend the university’s ‘Brain performance and nutrition research centre’ on three occasions: an initial screening and training session, followed by further testing sessions lasting just over two hours each, during which participants will be asked to carry pout various cognitive tasks.

Research lead Timothy Eschle said: “There are a number of benefits to consuming red grapes. A specific extract from the skin of red grapes, resveratrol, has been found to increase blood flow to the brain and in some cases, increase mental performance on cognitive tasks.
