WebDec 11, 2024 · The neural signature of phosphene perception became apparent after 160 ms in widespread occipitoparietal areas. The authors concluded that widespread recurrent interactions are involved in phosphene perception, rather than a brief, early, local neural signature. In principle, this might encourage us to think that neural correlates of … WebJun 11, 2004 · The pressure phosphene tonometer (PPT), Proview™ eye pressure monitor (Bausch & Lomb Inc., Tampa, FL, USA), is a spring compression device calibrated in millimetres of mercury and consists of a ... tnt the inside story
