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 ...

Measuring Optokinetic Reflex and Vestibulo-Ocular Reflex in Unilateral Vestibular Organ Damage Model of Zebrafish

Journal of the Association for Research in Otolaryngology
One-sided vestibular disorders are common in clinical practice; however, their models have not been fully established. We investigated the effect of unilateral or bilateral deficits in the vestibular organs on the vestibulo-ocular reflex (VOR) and optokinetic reflex (OKR) of zebrafish using in-house equipment.

Effect of the Acoustic Reflex on Inner Ear Damage Induced by Industrial Noise

Acta Oto-Laryngologica, 1983
Shipyard noise is a variable noise which induces permanent threshold shift (PTS) in exposed workers. In humans, the stapedius reflex has been found to be very stable in this type of exposure. Temporary threshold shift (TTS) in the absence of stapedius reflex has been found to extend downwards through the speech-frequencies instead of showing a high ...

The middle ear muscle reflex: Current and future role in assessing noise-induced cochlear damage

The Journal of the Acoustical Society of America, 2023
The middle ear muscle reflex (MEMR) in humans is a bilateral contraction of the middle ear stapedial muscle in response to moderate-to-high intensity acoustic stimuli. Clinically, MEMR thresholds have been used for differential diagnosis of otopathologies for decades.

H-reflex modulations during voluntary and automatic movements following upper motor neuron damage

Electroencephalography and Clinical Neurophysiology/Electromyography and Motor Control, 1998
It is not known whether similar mechanisms account for the impairments of voluntary movement and automatic postural responses of individuals with spasticity secondary to damage to the sensorimotor cortex and its projections (i.e. upper motor neuron syndrome (UMN)).The present study examined changes in soleus H-reflexes preceding and during voluntary ...

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 ...

Eye gaze does not produce reflexive shifts of attention: Evidence from frontal-lobe damage

Neuropsychologia, 2006
Humans are able to predict the behavior of others using visual information. Several studies have argued that social cues, such as eye gaze direction, can influence the allocation of visual attention in a reflexive manner. We have previously shown that a patient with frontal-lobe damage, patient EVR, can use peripheral cues to direct attention but ...

Prevention of Hemolysis-Induced Organ Damage by Nutritional Activation of the Vagal Anti-Inflammatory Reflex*

Critical Care Medicine, 2013
Acute hemolysis is associated with organ damage, inflammation, and impaired vascular function. Stimulation of the cholecystokinin-1 receptor-dependent vagal anti-inflammatory reflex with lipid-rich enteral nutrition was demonstrated to prevent tissue damage and attenuate inflammation. This study investigates the effects of nutritional activation of the

Acute Effects of Lingual Nerve Damage on Orofacial Nociceptive-Induced Reflexes

Journal of Oral and Maxillofacial Surgery, 2005
PC12 cells were found to attach on PLGA nerve conduits coated with FNIII9-10 peptide best among all the groups. PC12 cells showed better cellular attachment on nerve conduit in proportion to FNIII9-10 peptide concentration. 3) The SEM view of cell-nerve conduit complexes showed that some cells in all the groups seemed to be morphologically changed from

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)
