The National Centre for Mental Health is appealing for people who have mental health problems to join their Welsh research network.
People who have conditions such as Autism, Post Traumatic Stress Disorder and Alzheimer's disease, are being asked to volunteer. Being part of the Wales Mental Health Network will involve taking part in studies aimed at improving understanding about why people experience mental health problems.
The NCMH says people who apply will be asked to take part in an informal, confidential 20 minute interview - often in their own home or at their local GPs- with one of the researchers.
It's hoped about 6,000 people will be recruited onto the network
Wales' Chief Scientific Adviser, Professor John Harries, says the £50-million investment should help build a team of top-level scientists and attract the best research projects to Wales.
First Minister Carwyn Jones is set to announce a £50m package to attract 'star' scientists to Wales, as way of boosting research and science's contribution to the Welsh economy.
The money - £10m a year for the next five years - would form a scheme called Sêr Cymru (Star Wales). It would also develop research networks to help scientists make more successful bids for funding.
The funding comes as a result of a report by Wales' first Chief Scientific Adviser, Professor John Harries, and will be focused on three areas:
Life sciences and health
Low carbon, energy and environment
Advanced engineering and materials
Minister for Business, Technology and Science Edwina Hart said the money would strengthen "the vital links between the research and science skills base" in Wales.
