讲座摘要：

Cases of visual awareness without a corresponding stimulus occur in special conditions, such as pathological hallucinations, dreaming, mental imagery, synaesthesia and some illusions. Hallucinations can also be perceived as sweeping waves of visibility that occur when exposed to full field luminance flicker. However, a primary problem with such percepts is the inability to objectively measure the ‘hallucinated’ content. Here, I will talk about new methods to objectively measure two different types of visual phantom perception: mental imagery and flicker induced hallucinations. Using perceptual methods, we have shown that visual phantoms or non-retinal vision can be local in visual space, undergo adaptation and priming, are linked to visual cortex anatomy, and can even be bistable. These new methods provide novel tools to investigate the constructive nature of visual awareness in function and dysfunction.
