I'm curious about information on the flicker fusion threshold relative to conscious vision and that which we are not conscious of.
More specifically, I am curious because I have an interest in vestibular dysfunction and know that those who have multiple cuncussive syndrome also suffer from the strobe effect of flourescent lighting and some computer monitors. So it seems that these stimuli are within the flicker fusion threshold for most of us, yet we are still unconsciously affected by the flicker that we cannot consciously see.
Anyone have any information or leads?

Re: Flicker fusion threshold
Mon, January 16, 2006 - 10:56 PMI've actually had a few discussions with people on this issue. I'm currently studying how electrical stimulation is integrated in the time domain in patients that suffer from RP. We have a prosthetic device we use to electrically stimulate the retina. My theory, and some of the people I talk to tend to agree, is that flicker fusion is set by early visual processing (retina) rather than later areas. If my little theory holds true, flicker fusion would just be a result of temporal integration and any "additional information" would be lost. However, I already call bullshit on what I just said (sort of) since the ganglion cells can fire upwards of 200-250 Hz.
I would suggest looking into synchrony and contour binding.
As far as computer monitors, they are just barely beyond the CFF point. I can, for example, see a flickering monitor if I look at it in my periphery.
