On the existence and the role of chaotic processes in the nervous system

Abstract: Chaos theory is a rapidly growing field. As a technical term, "chaos" refers to deterministic but unpredictable processes being sensitively dependent upon initial conditions. Neurobiological models and experimental results are very complicated and some research groups have tried to pursue the "neuronal chaos". Babloyantz's group has studied the fractal dimension (d) of electroencephalograms (EEG) in various physiological and pathological states. From deep sleep (d = 4) to full awakening (d > 8), a hierarchy of… Show more

“…While all parts of such a system are interconnected, it is nevertheless possible to break out subsystems ͑represented by subsets of the phase space͒ that are only loosely coupled to one another. 17 Thus blood flow is only indirectly related to the dynamic of speaking; the process of alcohol dehydrogenase regulation is ͑we hope͒ largely unrelated to that of automobile driving. Walking and gum chewing are mostly unconnected.…”

“…Besides its power and beauty in depicting morphological fractal objects (e.g., see Mandelbrot 1983;Barnsley 1993;Peitgen et al 2004; and see a mini review of applications in brain morphology in Liu et al 2003a), FD has also been proved successful in quantifying the complexity of dynamic fluctuations in time-series signals such as electroencephalographic (EEG) data (Arle and Simon 1990;Lutzenberger et al 1992Lutzenberger et al , 1995Pradhan and Dutt 1993). Furthermore, it has been used to examine signal irregularities in diseases such as epilepsy (Doyon 1992;Bullmore et al 1994;Uritskii et al 1999;Esteller et al 2001), Alzheimer's disease (Woyshville and Calabrese 1994;Besthorn et al 1995Besthorn et al , 1996 and frontal lobe dementia (Besthorn et al 1996).…”
