Rhythmogenic neuronal networks, pacemakers, and k-cores
Neuronal networks are controlled by a combination of the dynamics of individual neurons and the connectivity of the network that links them together. We study a minimal model of the preBotzinger complex, a small neuronal network that controls the breathing rhythm of mammals through periodic firing bursts. We show that the properties of a such a randomly connected network of identical excitatory...
متن کاملReorganization of Pontine Rhythmogenic Neuronal Networks in Krox-20 Knockout Mice
We have shown previously that the inactivation of the zinc finger gene Krox-20 affects hindbrain segmentation, resulting in the elimination of rhombomeres 3 and 5. We demonstrate here that Krox-20 homozygous mutant mice exhibit abnormally slow respiratory and jaw opening rhythms, indicating that a modification of hindbrain segmentation influences the function of neuronal networks after birth. C...
متن کاملRhythmogenic effects of weak electrotonic coupling in neuronal models.
Strong gap-junctional coupling can synchronize the electrical oscillations of cells, but we show, in a theoretical model, that weak coupling can phase lock two cells 180 degrees out-of-phase. Antiphase oscillations can exist in parameter regimens where in-phase oscillations break down. Some consequences are (i) coupling two excitable cells leads to pacemaking, (ii) coupling two pacemaker cells ...
متن کاملDynamical Hehaviour of Phase Oscillator Networks on the Bethe Lattice
We study the dynamical nature of phase oscillator networks on a Bethe lattice. We derive self-consistent equations for the cavity fields (i.e. the oscillator probability distributions) by using the cavity method both in equilibrium and via an analytic approximation for nonequilibrium states. The order parameters and their evolution equations are obtained as functions of the cavity fields. The t...
متن کاملPhase Separation of Binary Fluids with Dynamical Temperature
Thermal phase separation process, which follows a sudden quench in the coexistence region, is considered for binary fluid mixtures. It is studied applying a new version of an hybrid lattice Boltzmann model, where non-ideal terms of the pressure tensor, which takes into account thermal and concentration gradient contribution, are included as a body force in the LBM equations, used to solve the N...
