We construct a model that predicts the statistical properties of spike trains generated by a sensory neuron. The model describes the combined effects of the neuron's intrinsic properties, the noise in the surrounding, and the external driving stimulus. We show that the spike trains exhibit universal statistical behavior over short times, modulated by a(More)
Understanding a neural code requires knowledge both of the elementary symbols that transmit information and of the algorithm for translating these symbols into sensory signals or motor actions. We show that these questions can be separated: the information carried by any candidate symbol in the code--- a pattern of spikes across time or across a population(More)
An experimental full screen editor has been written in APL for IBM 3270 display terminals, based on the following principles: • a small command repertoire, based on APL syntax • an undo facility for correcting mistakes • internal dependence upon a small number of editing primitives As written, the editor contains two major commands,(More)
APL includes a few primitives to permit searching of strings for single characters, principally the dyadic iota. APL2 adds iota underline. This latter function will find all occurrences of a given string in a longer string. Sometimes, however, more elaborate searching is needed; for example, searching for strings of variable length, searching for any of(More)
Phenotypic variability in a microorganism population is thought to be advantageous in fluctuating environments, however much remains unknown about the precise conditions for this advantage to hold. In particular competition for a growth-limiting resource and the dynamics of that resource in the environment modify the tradeoff between different effects of(More)
