    Area of Science:

    • Neuroscience
    • Information Theory
    • Computational Neuroscience

    Background:

    • Previous methods calculated information transfer in single-input, single-output neuronal systems.
    • Eckhorn and Poepel (1974) modeled neuronal channels as finite Markov chains.
    • Understanding information processing in complex neuronal networks remains a challenge.

    Purpose of the Study:

    • To develop a method for calculating transinformation in multiple-input, single-output neuronal systems.
    • To extend existing theoretical frameworks for analyzing neural information transfer.
    • To explicitly account for correlations between multiple input channels.

    Main Methods:

    • Extension of the finite Markov chain approach for neuronal spike trains.
    • Derivation of transinformation formulae analogous to linear systems theory.
