Adopting a model-based approach, this work develops procedures to quantify and properly normalize the classical joint peristimulus time scatter diagram and generalizes the classical measures for quantifying a direct interneuronal connection to include possible stimulus-locked time variations.

Neuronal spike trains and stochastic point processes. I. The single spike train.
The statistical techniques available for the analysis of single spike trains are described and related to the underlying mathematical theory, that of stochastic point processes, whose realizations may be described as series of point events occurring in time, separated by random intervals. Expand
Neuronal spike trains and stochastic point processes. II. Simultaneous spike trains.
The statistical analysis of two simultaneously observed trains of neuronal spikes is described, using as a conceptual framework the theory of stochastic point processes, and the theory presented is illustrated by an application to experimentally obtained data from auditory neurons. Expand
RANDOM WALK MODELS FOR THE SPIKE ACTIVITY OF A SINGLE NEURON.
Quantitative methods for the study of the statistical properties of spontaneously occurring spike trains from single neurons suggest a number of descriptive mathematical models that can describe a wide range of neuronal activity in terms of two parameters. Expand
Detecting spatiotemporal firing patterns among simultaneously recorded single neurons.
An algorithm that rapidly finds all single or multineuron patterns that repeat two or more times within a block of data, as well as equations for calculating the number of patterns of given length and repetition that would be expected. Expand
Feature-linked synchronization of thalamic relay cell firing induced by feedback from the visual cortex
It is reported that when driven by moving oriented visual stimuli the cortical feedback induces correlated firing in relay cells, and proposed that this feedback loop serves to lock or focus the appropriate circuitry onto the stimulus feature. Expand
Simultaneously Recorded Trains of Action Potentials: Analysis and Functional Interpretation
A new kind of statistical display, the joint peri-stimulus-time scatter diagram, facilitates the analysis and interpretation of two or more simultaneously recorded trains of action potentials. The… Expand
On the significance of correlations among neuronal spike trains
It is possible to compare stimulus-locked, and therefore time dependent correlations for different stimuli and also for different times relative to stimulus onset, and to separate purely stimulus-induced correlation from intrinsic interneuronal correlation. Expand

The concept of neuronal assembly as it has appeared in selected portions of the literature is examined and it is shown that the dynamic firing correlation can be caused either by dynamic changes in neuronal connection strengths or by the effects of an unobserved (large) pool of other neurons.

Evaluation of neuronal connectivity: Sensitivity of cross-correlation
It appears that indeed the sensitivity of cross-correlation for excitation is larger to an order of magnitude than it is for inhibition, and the relation to commonly used methods to measure strength of interaction are discussed. Expand
