Raynaud's phenomenon and thermal entrainment: an objective test.
A new objective test for diagnosing Raynaud's phenomenon was assessed in practice. The test is based on entrainment of the thermal vasomotor control system and entails non-invasive measurement of blood-flow responses in one hand while alternating thermal stimuli are applied to the contralateral hand. A significant (p less than 0.001) abnormality of vasomotor control was found in patients with R...
متن کاملEntrainment as an electrophysiologic phenomenon.
Waldo and his colleagues at the University of Alabama (1-3) observed that a critical rate of pacing was required to terminate atrial flutter. At the lower rates of pacing, continuation of the arrhythmia occurred immediately after cessation of pacing. Their observations had important clinical implications, including the recommendation for systematic prophylactic implantation of electrodes during...
متن کاملNeural Entrainment to the Beat: The "Missing-Pulse" Phenomenon.
Most humans have a near-automatic inclination to tap, clap, or move to the beat of music. The capacity to extract a periodic beat from a complex musical segment is remarkable, as it requires abstraction from the temporal structure of the stimulus. It has been suggested that nonlinear interactions in neural networks result in cortical oscillations at the beat frequency, and that such entrained o...
متن کاملAlpha entrainment is responsible for the attentional blink phenomenon
The attentional blink phenomenon is the reduced ability to report a second target (T2) after identifying a first target (T1) in a rapid serial visual presentation (RSVP) of stimuli (e.g., letters), which are presented at approximately 10 items per second. Several explanations have been proposed, which focus primarily on cognitive aspects, such as attentional filter-, capacity limitation- and re...
متن کاملDegree of Skin Denervation and Its Correlation to Objective Thermal Sensory Test in Leprosy Patients
BACKGROUND Leprosy is an infectious disease affecting skin and peripheral nerves resulting in increased morbidity and physical deformities. Early diagnosis provides opportune treatment and reduces its complications, relying fundamentally on the demonstration of impaired sensation in suggestive cutaneous lesions. The loss of tactile sensitivity in the lesions is preceded by the loss of thermal s...
