Zusammenfassung: | Visual hallucinations and related phenomena, such as deja vu, are reminders that conscious perception does not always accurately reflect external reality. We might be startled by a garden hose that at first glance looks like a snake, or feel an eerie sense of familiarity in new surroundings. For the most part these are transitory and intriguing perceptual glitches, yet in many neuropsychiatric disorders they are recurrent and troubling symptoms. Currently there is no unified brain-behavior framework to conceptualize these phenomena. The work by Megevand and colleagues (2014), which uses intracranial EEG to discern the neural correlates of topographic visual hallucinations and deja vu in the parahippocampal place area, is timely and informative, hinting at a mechanism for these phenomena involving interactions between large-scale neural networks. |
