چکیده
| Many scientists believe that all pulse-coupled neural networks are toy models that are far away from the biological reality. We show here, however, that a huge class of biophysically detailed and biologically plausible neu-ral network models can be transformed into a canonical pulse-coupled form by a piece-wise continuous, possibly non-invertible, change of variables. Such transformations exist when a network satisses a number of conditions; e.g. it is weakly connected; the neurons are Class 1 excitable (i.e., they can generate action potentials with an arbitrary small frequency); and the synapses between neurons are conventional (i.e. axo-dendritic and axo-somatic). Thus, the diierence between studying the pulse-coupled model and Hodgkin-Huxley-type neural networks is just a matter of a coordinate change. Therefore, any piece of information about the pulse-coupled model is valuable since it tells something about all weakly connected networks of Class 1 neurons. For example, we show that the pulse-coupled network of identical neurons does not synchronize in-phase. This connrms Ermentrout's (1996) result that weakly connected Class 1 neurons are diicult to synchronize, regardless of the equations that describe dynamics of each cell.

متن کاملUsing Directional Fibers to Locate Fixed Points of Recurrent Neural Networks.
We introduce mathematical objects that we call ``directional fibers,'' and show how they enable a new strategy for systematically locating fixed points in recurrent neural networks. We analyze this approach mathematically and use computer experiments to show that it consistently locates many fixed points in many networks with arbitrary sizes and unconstrained connection weights. Comparison with...
