چکیده

Disruptions of the circadian rhythm are associated with internal desynchronization. It affects some functions our body and behavior that important to health. Our modern lifestyle has contributed millions people developing disruptions, making subject very clinically as well economically. Motivated by studying a simple mathematical model can reveal features synchronization desynchronization, in this contribution, we extend coupling oscillator phase proposed Strogatz [14] sense memory is considered modeling. Such result introduction Caputo-type fractional derivatives oscillators’ dynamics, resulting model. We show well-posed. Furthermore, analyzethe phenomena. obtain synchronized solutions explicitly when equally distributed between oscillators. In contrast, distinct levels imposed modeling, lower upper bounds because any existing solution must be confined between. present numerical realizations support theoretical findings great detail.

Human sleep and circadian rhythms: a simple model based on two coupled oscillators.

We propose a model of the human circadian system. The sleep-wake and body temperature rhythms are assumed to be driven by a pair of coupled nonlinear oscillators described by phase variables alone. The novel aspect of the model is that its equations may be solved analytically. Computer simulations are used to test the model against sleep-wake data pooled from 15 studies of subjects living for w...

Synchronization of two coupled fractional-order chaotic oscillators

The dynamics of fractional-order systems have attracted increasing attentions in recent years. In this paper, the synchronization of two coupled nonlinear fractional order chaotic oscillators is numerically demonstrated using the master–slave synchronization scheme. It is shown that fractional-order chaotic oscillators can be synchronized with appropriate coupling strength. 2005 Elsevier Ltd. A...

Synchronization and entrainment of coupled circadian oscillators.

Circadian rhythms in mammals are controlled by the neurons located in the suprachiasmatic nucleus of the hypothalamus. In physiological conditions, the system of neurons is very efficiently entrained by the 24 h light-dark cycle. Most of the studies carried out so far emphasize the crucial role of the periodicity imposed by the light-dark cycle in neuronal synchronization. Nevertheless, heterog...

Spontaneous synchronization of coupled circadian oscillators.

In mammals, the circadian pacemaker, which controls daily rhythms, is located in the suprachiasmatic nucleus (SCN). Circadian oscillations are generated in individual SCN neurons by a molecular regulatory network. Cells oscillate with periods ranging from 20 to 28 h, but at the tissue level, SCN neurons display significant synchrony, suggesting a robust intercellular coupling in which neurotran...

Adaptive Fractional-order Control for Synchronization of Two Coupled Neurons in the External Electrical Stimulation

This paper addresses synchronizing two coupled chaotic FitzHugh–Nagumo (FHN) neurons with weakly gap junction under external electrical stimulation (EES). To transmit information among coupled neurons, by generalization of the integer-order FHN equations of the coupled system into the fractional-order in frequency domain using Crone approach, the behavior of each coupled neuron relies on its pa...
