Spiking is the common form of action adopted by neurons which cumulatively creates the notion of activity in the nervous system. Any attempt on defining a neural activity in the form of information processing and organization requires studying what individual spikes or spiking represents towards the definition in question. In order to define and discuss the representation abilities of spikes, the problem of deterministically coding a continuous time signal using an ensemble of spike trains is addressed. Coding is, with an eye toward "efficiency", defined as a trade-off between the number of spikes in the code and the quality of the code operationalized using the notion of reconstruction error. It is shown that inverting the coding model leads to a reconstruction procedure that amounts to a constrained optimization problem. A class of coding models is considered that makes the coding procedure biologically plausible while at the same time making the reconstruction problem tractable. It is demonstrated that the reconstruction error depends acutely on the coding model. This tight coupling is then used to describe a procedure that learns a coding model of improved efficiency. Experiments on speech data show the performance of the coding described.
