Abstract

Methylphenidate influenced the spontaneous autonomic activity of children diagnosed as hyperactive. There was dose response related reduction in disruptive classroom behavior monitored by the teacher ratings and a parallel decrease in a component of heart period variability, V, derived via spectral analysis of heart period activity. A low dose of methylphenidate, which has been reported to enhance cognitive performance, selectively increased a measure of respiratory‐cardiac coupling, Cw, derived via cross‐spectral analysis of respiration and heart period activity. It is hypothesized that Cw may be a quantitative manifestation of brainstem integration and V may be a quantitative estimate of effective vagal tone on the heart.
