Study into positive effects of red wine
Researchers at the University of Northumbria are seeking volunteers for two studies, who'll be paid as much as £65 (€75), 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 out 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.
"Most studies have been carried out in young adults at the peak of their cognitive abilities, thus the benefits of resveratrol are expected to be more prominent in older adults who may suffer a slight natural decline in certain aspects of mental function such as memory and reaction time.
"We also want to establish whether resveratrol can affect mental function at altitude, which often impacts on people's performance."
Volunteers won't actually be called on to drink red wine - the resveratrol will be administered in capsule form.
