WebSignificance: Mayer waves are spontaneous oscillations in arterial blood pressure that can mask cortical hemodynamic responses associated with neural activity of interest. Aim: We aim to characterize the properties of oscillations in the functional near-infrared spectroscopy (fNIRS) signal generated by Mayer waves in a large sample of fNIRS recordings. Web21 mei 2011 · The origin of Mayer waves is of particular clinical interest since they present in healthy young human subjects under certain experimental conditions but are absent in older subjects. This has led to the conclusion that they may be due to an age-related reduction in sympathetic and parasympathetic efferent neuronal function ( Jarisch et al., …

Mayer waves are cyclic changes or waves in arterial blood pressure brought about by oscillations in baroreceptor and chemoreceptor reflex control systems. The waves are seen both in the ECG and in continuous blood pressure curves and have a frequency about 0.1 Hz (10-second waves). These waves were originally described by Siegmund Mayer, Ewald Hering and Ludwig Traube hence originally called "Traube–Hering–Mayer waves".
