Attaining and maintaining criticality in a neuronal network model

Peng, Jiayi; Beggs, John M. - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 7, pp. 1611-1620

We propose a cellular automaton model for neuronal networks that combines short-term synaptic plasticity with long-term metaplasticity. We investigate how these two mechanisms contribute to attaining and maintaining operation at the critical point. We find that short-term plasticity, represented...

White noise-induced spiral waves and multiple spatial coherence resonances in a neuronal network with type I excitability

Gu, Hua-Guang; Jia, Bing; Li, Yu-Ye; Chen, Guan-Rong - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 6, pp. 1361-1374

White noise-induced pattern formation is studied in a network composed of Morris–Lecar neuronal models with type I excitability and with initial values higher than that of the resting potential. The appearance and disappearance of spiral waves, as well as the transitions between spiral wave...

Geometrical structure of the neuronal network of Caenorhabditis elegans

Morita, Satoru; Oshio, Ken-ichi; Osana, Yuko; … - In: Physica A: Statistical Mechanics and its Applications 298 (2001) 3, pp. 553-561

The neuronal network of the soil nematode Caenorhabditis elegans (C. elegans), which is a good prototype for biological studies, is investigated. Here, the neuronal network is simplified as a graph. We use three indicators to characterize the graph; vertex degree, generalized eccentricity (GE),...

Wiring cost in the organization of a biological neuronal network

Ahn, Yong-Yeol; Jeong, Hawoong; Kim, Beom Jun - In: Physica A: Statistical Mechanics and its Applications 367 (2006) C, pp. 531-537

To find out the role of the wiring cost in the organization of the neuronal network of the nematode Caenorhabditis elegans, we build the spatial neuronal map of C. elegans based on geometrical positions of neurons. We show that the number of interneuronal connections of the Euclidean length d...

Dynamics of intracellular Ca2+ oscillations in the presence of multisite Ca2+-binding proteins

Chignola, Roberto; Del Fabbro, Alessio; Milotti, Edoardo - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 16, pp. 3172-3178

We study the dynamics of intracellular calcium oscillations in the presence of proteins that bind calcium on multiple sites and that are generally believed to act as passive calcium buffers in cells. These multisite calcium-binding proteins set a sharp threshold for calcium oscillations, and...

Coherence resonance induced by non-Gaussian noise in a deterministic Hodgkin–Huxley neuron

Gong, Yubing; Xie, Yanhang; Hao, Yinghang - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 18, pp. 3759-3764

In this paper, we report a novel effect of a particular kind of non-Gaussian noise (NGN), especially its deviation from Gaussian noise, on the spiking activity in a deterministic Hodgkin–Huxley (HH) neuron. It is found via numerical simulations that the coefficient of variation (CV),...
