[Cross-correlation as a method for discriminating impulses on multineuronal recordings].

A V Bogdanov, A G Galashina

    Summary

    Analyzing neural activity using cross-correlation histograms, this study confirms that "window" discrimination of impulse series is valid. The analysis step, not the window size, is key to identifying direct neuronal connections.
