Video of GY filmed in 1989 of his mimicry by arm movements of the paths and directions of moving stimuli. From an unpublished study by John Barbur, Arash Sahraie, and Larry Weiskrantz. A summary of the procedure and the successfully followed paths can be found in Weiskrantz, Curr. Dir. Psychol. Sci., 1995, 4: 146-151. His non-responding to slowly moving stimuli led to a further study in which he was found to have excellent discrimination for the direction of slow movements in the complete absence of acknowledged awareness (cf. Weiskrantz, Barbur and Sahraie, Proc. Natl. Acad. Sci., 1995, 92: 6122-6126), and this in turn led to a further brain imaging study revealing a brain area associated with awareness or its absence for fast vs. slowly moving stimuli (Sahraie, Weiskrantz, Barbur, Simmons, Williams, and Brammer, Proc. Natl. Acad. Sci., 1997, 94: 9406-9411.).
