- Primary Outcome Measures
Name Time Method <p>The main study parameters are the behavioural performance on visual tests and<br /><br>the cortical activation (commonly referred to as the BOLD response) associated<br /><br>with processing visual information.</p><br>
- Secondary Outcome Measures
Name Time Method <p>Eye-movements will be analysed in order to control the fixation of the<br /><br>observers and to define the observer's eye-movement patern. Furthemore<br /><br>behavioral data will be used threshold measurement and to determine whether<br /><br>observers can detect and identify a stimulus.</p><br>
