For those who like the Science

25 years ago the Veterans Administration Department of the USA (Psychiatric Division) was doing very in depth studies of the visual/cognitive experiences related to Flickering light (aka stroboscopic light). This is just the Abstract of one study to give you a taste. If you have heard me talk about the Neuro Light design being based on Complex Adaptive Systems, this "dissipative structure" approach to the visual displays should "light up your Christmas tree". Yes, it is "hard science" but it is delicious if you have a "taste" for it.
PS - don't worry, I will also be posting stuff that is not so hard core

The stroboscopic patterns as dissipative structures

Stwertka SA

Photic stimulation of the human visual system with uniform but intermittent illumination has been recognized for well over a century to give rise to the perception of complex visual patterns and forms. A review of the literature pertaining to these "stroboscopic patterns" is presented, along with a reviewof theories addressing their origins. The theories range from attributing the patterns to inhomogeneities in the structure of the eye, to the formation of functional domains of neural activity. A novel account of the origins of the patterns is developed in this paper utilizing advances in the neurobiology of information processing and non-linear dynamics. This view conceptualizes the patterns as examples of "dissipative structures." These dissipative structures are conceived of as self-organizing macro states of spatio-temporal coherence, widespread among visual cortical neurons. This self-organization is described in terms of nonlinear dynamics, in which sets of attractors emerge within a neural phase space undergoing constant change as the energy contained within successive volleys of stimulation- induced action currents is recursively dissipated by the visual system through cooperative feedback. The trajectories of activity formed by these attractors may reflect the actual form of the perceived patterns themselves and are thought to correspond to some of the reported properties of "linking fields" in the visual cortex.
