**network model**

Blocking stable motifs may obstruct specific attractors | A Boolean network model of cytotoxic T cell signaling that reproduces the known experimental results of these T cells in the context of T-LGL leukemia was previously constructed by Zhang et al. |

Blocking stable motifs may obstruct specific attractors | This network model consists of 60 nodes and 142 regulatory edges, with the nodes representing genes, proteins, receptors, small molecules, external signals (e.g. |

Blocking stable motifs may obstruct specific attractors | This result agrees with previous studies of T-LGL leukemia, in which it was found that blocking SIP signaling induced apoptosis in leukemic T-LGL cells [28, 47] , a result reproduced by the network model when the state of SIP was set to OFF [41, 46]. |

Discussion | In this work we proposed a network control approach that combines the structural and functional information of a discrete (logical) dynamic network model to identify control targets. |

Discussion | We illustrated our methods potential to find intervention targets for cancer treatment and cell differentiation by applying it to network models of T-LGL leukemia and helper T cell differentiation. |

Introduction | Logical dynamic network models [31—38] consist of a set of binary variables {0,}, i = 1,2,. . |

Introduction | None of the networks we discuss in this work nor any intracellular network models we are aware of fall in this category; for more details see 81 Text, 82 Text, and ref [41].) |

Stable motif control implies network control | Intervention targets for each control strategy in the T-LGL leukemia network model . |

The control targets transcend the logical modeling framework | To address this, we translate the studied Boolean network models into ordinary differential equation (ODE) models using the method described by Wittmann et al. |

Abstract | Here, we used both a reduced firing rate model and numerical simulations of a spiking network model of the striatum to analyze the dynamic balance of spiking activities in D1 and D2 MSNs. |

Effect of GPe induced disinhibition of FSI activity on the DTT | The effect of GPe on FSIs was modelled in our network model as a constant amount of inhibition on FSI firing rates. |

Effect of cortical spiking activity correlations on the DTT | These simulations were only performed for the spiking neural network model since modelling correlations in a mean field model is nontrivial, especially when post-synaptic neurons are recurrently connected. |

Introduction | Here we describe the effect of the heterogenous connectivity of D1 and D2 neurons on their mutual interactions using both a reduced firing rate model and numerical simulations of a spiking striatal network model . |

Modulation of the DTT by dopamine | Apart from the obvious simplicity of our network model , we think there might be an additional reason for this. |

Network Simulations | The striatal network model was based on the spiking network model of the striatum as described in [12] , except that the network connectivity was not considered to be homogeneous as in [12]. |

Network Simulations | The parameter values for both MSNs and F813 in our network model are summarized in Table 3. |

Confirmation of node degree/directionality relationship in human EEG networks during conscious and unconscious states | Our analysis demonstrated that: (1) the theoretical predictions made from computational human brain models regarding the relationship between node degree and dPLI are supported by patterns observed in empirical EEG networks recorded from waking and unconscious states (in Fig 5A and 5B); (2) The functional brain network of the whole frequency band (0.5—55HZ) is highly correlated with the node degree distribution found in the anatomical brain network model . |

Discussion | simulated how network structure affects the phase lead/lag relationship between brain regions in a realistic brain network model [19]. |

Discussion | showed in a network model that if two nodes are symmetrically located within a given network topology, the dynamics of the nodes will be fully synchronized even at a significant distance [53]. |

Discussion | This relationship, derived from simple oscillator models, was applied successfully to complex brain network models generated computationally or reconstructed empirically. |

Identification of mathematical relationships among node degree, amplitude of local oscillations and directionality of interactions | We proceeded by constructing a simple coupled oscillatory network model , using a Stuart-Landau model oscillator to represent the neural mass population activity at each node of the network (see Materials and Methods, and 81 Text for details). |

Introduction | The directionality of interactions between nodes was studied through the modulated phase lead/lag relationship of coupled oscillators in general network models, large-scale anatomical brain network models and empirically-reconstructed networks from high-density human EEG across different states of consciousness (Fig 1). |
