An installation for the multiplexed transmission of signals from seismic receivers, each associated with a respective multiplexing circuit, connected in series in a transmission line between a generator of first pulse signals and a registration station. Each receiver is followed by a digitiser and each multiplexing circuit includes means allowing the first pulse signals to pass without modification, at least one shift register, capable of being filled with digital information from the associated...

Abstract Important advances in experimental methods have made it possible to measure the electrical events in dendrites directly and to record optically from dendritic spines. These new techniques allow us to focus on the input region of the neuron and highlight the excitable properties of the dendritic membrane. Interestingly, some of the recent experimental findings were anticipated by earlier theoretical research, for example, the observation that some spines possess excitable channels that m...

1. We have investigated the theoretical and practical problems associated with the interpretation of time constants and the estimation of electrotonic length with equivalent cylinder formulas for neurons best represented as multiple cylinders or branched structures. Two analytic methods were used to compute the time constants and coefficients of passive voltage transients (and time constants of current transients under voltage clamp). One method, suitable for simple geometries, involves analytic...

Publisher Summary This chapter focuses on different electrotonic models of neuronal dendrites and single neuron computation to reduce the number degrees of freedom. The areas that help in reducing the degrees of freedom include the importance for modeling studies of having good estimates of the electrotonic structure of a cell, the dynamic range of computational possibilities available to a neuron, by considering its possible resting states, assuming that a real neuron ever can be considered to ...

This talk briefly reviewed results of earlier computations that simulated synaptic inputs to passive dendritic membrane. Then it reviewed dendritic spines and the possibility that some spine heads might have excitable membrane properties. Because some neurons have dendritic arbors that are studded with hundreds or thousands of spines, computations were used to explore theoretical examples of different synaptic input combinations to both excitable and passive spines. The results demonstrate the p...
