The enigma of Mayer waves: Facts and models.
Mayer waves are oscillations of arterial pressure occurring spontaneously in conscious subjects at a frequency lower than respiration (approximately 0.1 Hz in humans). Mayer waves are tightly coupled with synchronous oscillations of efferent sympathetic nervous activity and are almost invariably enhanced during states of sympathetic activation. For this reason, the amplitude of these oscillatio...

متن کاملPatterns of sympathetic neuron activity associated with Mayer waves.
PREISS, GEORGE, AND CANIO POLOSA. Patterns of sympathetic neuron activity associated with Mayer xqaues. Am. J. Physiol. 226(3) : 724-730. 1974.-In Nembutal-anesthetized or decerebrate cats Mayer waves were evoked by bleeding and common carotid artery occlusion. The temporal patterns of sympathetic preganglionic neuron activity associated with the waves were essentially similar to those observed...

Physiol. 217(5) : 1375-l 383. 1969.Systemic blood pressure oscillations, produced in paralyzed dogs by arresting ventilation or by hemorrhage during mechanical ventilation, were related to the phasic phrenic nerve electrical activity. Oscillations syn...
متن کاملLee Waves and Mountain Waves ∗
Buoyancy perturbations develop when stably stratified air ascends a mountain barrier. These perturbations often trigger disturbances that propagate away from the mountain as gravity (or buoyancy) waves. Gravity waves triggered by the flow over a mountain are referred to as mountain waves or lee waves. Mountain waves sometimes reveal their presence through dramatic cloud formations, such as smoo...
