Researchers at the University of Durham are seeking healthy volunteers to participate in neuroimaging experiments using functional magnetic resonance imaging. The experiments will be performed at the York Neuroimaging Center using a 3Tesla magnet. We will start a new experiment in the next couple of weeks and participants will be asked to discriminate visual objects on the basis of their geometrical (shape) or surface (texture) features. Visual stimuli are images of 3D objects, and behavioural responses will be collected via button press. Typical sessions last for 1-2 hours, and involve lying still in the scanner while brain images are recorded. For detailed information about the experiment see attached file. The experiment is part of a research project based at the University of Durham. The experimenter is Dr. Cristiana Cavina-Pratesi and the main investigators are Prof. D. Milner; Prof. C. Heywood and Prof. R. Kentridge. If you are interested, read the information below and if you think to be eligible for participating, please fell free to contact Dr. Cristiana Cavina-Pratesi cristiana.cavina-pratesi(a)durham.ac.uk for further information. Your name will be entered in a database. You can decide to remove your name from the database at any time and you are always free to decline when an experimenter contacts you. To be eligible to participate, you must: a.. have no metal in your body (fillings are okay) b.. not be claustrophobic c.. be able to remain relatively still for periods of 5-8 minutes d.. be in good health and have no history of neurological disorders (e.g., epileptic seizures, head injuries) e.. be able to see without glasses (contacts are okay) at arms' length (for vision experiments); Thanks in advance for your attention Cristiana Cavina-Pratesi
