Six universities in Scotland have entered into a research collaboration to investigate conditions such as Alzheimer's disease and strokes.
Under the £40 million link-up, the institutions will share technology which is able to film the workings of the brain.
The universities of Edinburgh, Glasgow, Aberdeen, Dundee, St Andrews and Stirling are coming together with the aim of progressing treatment for brain conditions.
Joanna Wardlaw, professor of applied neuroimaging and honorary consultant neuroradiologist at the University of Edinburgh, commented: "This new collaboration will be internationally unique and will ensure an enhanced and competitive presence for Scotland in international research."
She added that joint working will enable progress which would be more difficult to achieve through working in isolation.
Meanwhile a study published in the Journal of the American Medical Association has indicated that vitamin B does not slow the progression of Alzheimer's disease.
It was found that high doses of the vitamin did not have a positive effect on the rate of decline experienced by patients with mild to moderate forms of the condition.
