Reduced reflex sensitivity persists several days after long-lasting stretch-shortening cycle exercise

Journal of Applied Physiology, 1999
The mechanisms related to the acute and delayed secondary impairment of the stretch reflex function were investigated after long-lasting stretch-shortening cycle exercise.

Alcohol binge-drinking damage on the vestibulo-oculomotor reflex

European Archives of Oto-Rhino-Laryngology, 2020
Binge drinking is associated with several adverse effects in multiple organs. This study aimed at evaluating the effects of a binge-like-drinking on the vestibulo-oculomotor reflex (VOR) using the video Head Impulse Test (vHIT) and the functional Head Impulse Test (fHIT).Eleven healthy men (age range 32-35 years) with moderate drinking habits and no ...

A ‘GAG’ reflex prevents repair of the damaged CNS

Trends in Neurosciences, 2008
The extracellular matrix of the central nervous system (CNS) serves as both a supporting structure for cells and a rich source of signaling molecules that can influence cell proliferation, survival, migration and differentiation. A large proportion of this matrix is composed of proteoglycans--proteins with long chains of polysaccharides, called ...

HABITUATION OF THE ORIENTING REFLEX IN BRAIN DAMAGED PATIENTS

Psychophysiology, 1971
ABSTRACTHabituation and dishabituation of the heart rate, skin conductance, and alpha blocking components of the orienting reflex to an auditory stimulus were examined for brain‐damaged and non‐brain‐damaged Ss. The non‐brain‐damaged group displayed the expected habituation for all of these response variables but the brain‐damaged group displayed ...

Conditioned motor reflexes in cats with damage to the hippocampus

Experimental Brain Research, 1972
Hippocampal damage in cats led to: a) A temporary suppression of previously elaborated motor feeding conditioned reflexes (CR); b) A retardation (nearly twice) in the rate of elaboration of a new CR; c) A marked prolongation of latency of CR; d) A disinhibition of negative CR.

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.

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 ...

Recovery of vestibulo-ocular reflex in vestibular neuronitis depending on severity of vestibulo-ocular reflex damage

Vestnik otorinolaringologii, 2019
The aim of this study is to evaluate clinical symptoms and recovery of vestibule-ocular reflex (VOR) in patients with vestibular neuronitis (VN) in dependence on severity of VOR damage according to video head impulse test (vHIT).45 patients with VN and superior or both superior and inferior vestibular nerves involvement were recruited and horizontal ...

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 ...

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)
