The electrical coupling between myocytes and fibroblasts the spacial distribution of within myocardial tissues are significant factors in triggering sustaining cardiac arrhythmias but their roles poorly understood. This article describes both direct numerical simulations an asymptotic theory propagation block excitation a model atrial tissue with myocyte-fibroblast coupling. In particular, thre...

an integrated model for magnetoencephalography (meg) and functional magnetic resonance imaging (fmri) is proposed. in the proposed model, meg and fmri outputs are related to the corresponding aspects of neural activities in a voxel. post synaptic potentials (psps) and action potentials (aps) are two main signals generated by neural activities. in the model, both of meg and fmri are related to t...
