The Unconditioned Orogastric Secretory Reflex
Reflex, Definition of. — Originating about the time of Descartes in the seventeenth century, the concept of reflex action grew in time into a most important principle for the interpretation of nervous operations. The founders of the reflex theory and their followers: Descartes (1) and Prokhaska …

THE IMPACT OF CONCUSSION HISTORY ON THE NEAR REFLEX AND PUPILLARY LIGHT REFLEX IN VIRTUAL REALITY
… light. These deficits also suggest that the near reflex triad, the joint response consisting of convergence, accommodation, and pupillary constriction associated with near vision, as well as the pupillary light reflex (PLR), hold promise as sensitive biomarkers. However, there has yet to be a …

Exercise Pressor Reflex Dysfunction in Hypertension
The exercise pressor reflex and its components, the muscle mechanoreflex and the metaboreflex, are overactive in hypertension. The mechanoreflex and metaboreflex are feedback mechanisms originating in skeletal muscle that increase mean arterial pressure (MAP) and heart rate (HR) during exercise. In …

Active database behaviour: the REFLEX approach
… on the ONTOS DBMS platform. The resultant REFLEX model was successfully ported and adapted onto a second POET platform. The porting process uncovered some interesting issues regarding preconceived ideas about the portability of open systems.

Electrical restoration of the micturition reflex
Numerous attempts at electrical stimulation of the detrusor muscle of the urinary bladder to evoke contraction and evacuation have been carried out over the past decade. A review of prostheses for the restoration of urinary continence and for effecting bladder evacuation, is given. Problems …

H-reflex changes with loading and unloading
Soleus H-reflex has been tested clinically in lying position. Stresses on the spine vary during lying, standing, weight lifting and unloading. This may influence the H-reflex. The purpose of this study was to measure the changes that might occur in the soleus H-reflex during such loading and …

Higher Order Conditioning of the Eyeblink Reflex
… an air puff to the eye ) that elicits an innate reflex blink response. A CS paired with the US at a fixed latency comes to elicit a predictive blink, if the CS begins sufficiently in advance of the US. A predictive blink is such that eyelid closure is maximal at the time of expected air puff …

Prolonged Lumbar Flexion Disturbs Paraspinal Reflex Behavior
… indicates that disturbance of paraspinal reflexes may limit spinal stability. The current study aimed to examine this behavior in humans. We hypothesized that prolonged lumbar flexion will disturb paraspinal reflex behavior in human subjects. Reflex behavior was quantified following a …

Presynaptic spinal reflex modulation in children and adolescents

Temperament and Character Correlates of the Startle Reflex
… temperament traits can modulate the startle reflex. There is evidence supporting Cloninger’s concept of Harm Avoidance as being predictive of individual differences in reactivity to aversive stimuli. (Corr, 1997). Since this finding, a new version Cloninger’s measure includes character …

The Effect of Masking on the Acoustic Reflex Threshold
… of masking noise on the threshold for stapedial reflex. It has been shown that masking which shifts the hearing threshold causes a loudness function typical of recruitment. It was hypothesized that the stapedial reflex threshold remains the same in a masked situation as in the unmasked situation …

Voluntary inhibition of reflex: Effects of consistent meditative practice
… of myocardial reactivity during a highly reflexive and stressful task. Meditative practice also predicted a rise in electrodermal activity during a relaxation task, contrary to expectations. These results support the concept that meditative practices may alter aspects of autonomic …
