Acoustic Reflex Measures of Cochlear Damage-A Normative Study

British Journal of Audiology, 1977
It has been argued that certain reflex measures may indicate the presence of end-organ hearing loss. It has been noticed that the difference between wide band noise and pure tone thresholds is diminished, that the reflex threshold duration function is flattened and that the reflex relaxation index, as specified by Norris et al.

Conditioned motor reflexes in cats with damage to the globus pallidus

Experimental Brain Research, 1971
1. Unilateral destruction of globus pallidus does not influence natural conditioned reflexes. Bilateral destruction results in temporary disappearance of natural as well as artificial conditioned motor reflexes. Further training is necessary for the reestablishment of these reflexes.

Reflex sympathetic dystrophy and early damage of carpal bones

Rheumatology International, 1985
A 56-year-old woman presented with changes characteristic of the reflex sympathetic dystrophy syndrome (RSDS) but also frank synovitis of the left wrist, an elevated ESR and early damage of the left carpus on radiographs, suggesting septic arthritis. A dynamic scan showed changes characteristic of RSDS.

The Formation and Extinction of Conditioned Reflexes in “Brain-Damaged” and Mongoloid Children

The Journal of Nervous and Mental Disease, 1959
The terms “brain-damaged” or “brain-injured” when applied to children refers to a combination of psychologic functions that are presumed to originate in pre-natal, peri-natal or infantile insults to the cerebrum. The category is entirely behavioral (4, 5) and implies that any of a number of kinds of cerebral damage will result in a common pattern of ...

Effect of amiridine on conditioned reflex in rats with damaged hippocampus

Bulletin of Experimental Biology and Medicine, 1997
It is shown that even after partial damage to the hippocampus in male rats by quinolinic acid, which causes selective degeneration of hippocampal neurons, their conditioned reflex to time remains impaired for a period of several months. Treatment with amiridine improves the learning of time-interval estimation by such rats and promotes compensatory ...

Comparative studies of the effects of some antimuscarinic agents on gastric damage and pupillary reflex in the rat [PDF]

British Journal of Pharmacology, 1984
The effects of some antimuscarinic compounds on oxotremorine‐induced gastric damage, the pupil size and the pupillary light reflex have been studied in the rat. Unlike atropine, propantheline and methylscopolamine, pirenzepine is effective in preventing gastric erosions at doses much lower than those that affect pupillary reflex.

Damage to the frontal and parietal lobes of the brain and conditioned reflexes in unconstrained subjects

Bulletin of Experimental Biology and Medicine, 1964
Higher nervous activity and motor disturbances were studied in three unconstrained dogs before and after in jury to the frontal or parietal lobes. There was no difference in the recovery time of conditioned reflex activity as between dogs with frontal or parietal lobe injury.

THE INCIDENCE OF THE GRASP REFLEX FOLLOWING HEMISPHERIC LESION AND ITS RELATION TO FRONTAL DAMAGE

Brain, 1992
The grasp reflex and related prehensile phenomena were investigated in two studies. In Study 1, 491 patients consecutively admitted to the neurological wards of our department were tested with a standardized procedure. Grasping was found in 8% of brain-damaged patients and occurred predominantly in patients with single (14 cases) or multiple (10 cases)

[Segmental reflexes after sciatic nerve damage in rats given thyroxine].

Neirofiziologiia = Neurophysiology, 1993
Amplitude of the L5 segmental reflex responses 20 min. before and after intraperitoneal introduction of obsidan, clopheline and finoptine was recorded in experiments on spinalized and thyroxinized rats which 3 weeks before have endured transection of the sciatic nerve.

Relationship between baroreceptor reflex function and end-organ damage in spontaneously hypertensive rats

American Journal of Physiology-Heart and Circulatory Physiology, 1999
The purpose of this study was to further illustrate the relationship between baroreceptor reflex sensitivity (BRS) and hypertensive end-organ damage (EOD) and to test the hypothesis that impairment of BRS aggravates EOD in hypertension. We studied baroreflex-mediated changes in heart rate [expressed as baroreceptor sensitivity to heart rate control ...
