Non-Markov negative correlation between interspike intervals in mammalian sympathetic efferent discharges

The background discharge of sympathetic efferent fibres in the hypogastric and splanchnic nerves of the cat was analyzed. Stationary discharges were renewal or had significant negative first order serial correlation coefficients. Negatively correlated discharges were non-Markov and the post-spike de...

Description
Summary:The background discharge of sympathetic efferent fibres in the hypogastric and splanchnic nerves of the cat was analyzed. Stationary discharges were renewal or had significant negative first order serial correlation coefficients. Negatively correlated discharges were non-Markov and the post-spike depression persisted for up to 5 s, covering the same time course as the prolonged inhibitory phenomena of sympathetic reflexes.
