You can specify the flicker pattern, and use the Philips Hue iPhone app to do a bunch more neat stuff, like change the lights to match the background color of a picture taken with the phone, for instance.
This is because the flicker pattern of the pursuit condition (Figure 4A) was not perceived to be stationary in the environment, but to be moving together with the tracking target.
Interestingly, a flicker pattern of 50 Hz presented to the eye can be perceived subliminally by the human mind and is also able to induce moments of awareness.
For example using the GR94a (C2) line one could record extracellularly from the dorsal organ and determine how the neuron responds to optical stimuli and in particular to their random flicker pattern of optical stimulation.
But human memory is far more like a desert mirage than a transcript – as we recall the past we are really just making meaning out of the flickering patterns of sights, smells and sounds we think we remember.
In this case, we observe binocular rivalry between flickering patterns, with perceptual alternations between the two eyes' images at a rate much slower than the flicker rate of the stimuli [11].
In the SSVEP assay, responses to flickering patterns are routinely recorded by an array of electrodes and their signals used to compute the visual sensitivity.
This provides quantitative support for the common anecdotal reports from migraineurs that they are bothered by a wide range of flickering patterns from fluorescent lights and television screens to sunlight viewed through trees from a moving automobile.
The new evidence appeared to answer some critics who have contended that previous findings of early modern human behavior in Africa have been spotty and short-lived — a "flickering" pattern of experimentation with little or no continuity over time and across regions.
The Verge reports that the squid skin seems to have two modes of behavior: a "flickering" pattern that mimics how water shimmers and may serve as camouflage, as well as a "flashing" mode which seems to occur only when other squid are nearby, leading the researchers to suspect it plays a role in communication.
