Comparison effect of pentobarbital sodium with chloral hydrate anesthesia on post-ischemic damage in an experimental model of focal cerebral ischemia
Introduction: Anesthetic agents, blood pressure, arterial pH and blood gases have found to influence on the pathophysiology of experimental stroke. Despite, there are very few comparative studies about effects of anesthetic agents in animal model of cerebral ischemia. Therefore, in this study, we investigated the effects of chloral hydrate and pentobarbital anesthesia, as comparative study, on...
متن کاملEffects of eye and head position on horizontal and vertical smooth pursuit.
PURPOSE To identify and explain the effects of eye and head position on smooth pursuit eye movements in normal humans. METHODS Horizontal and vertical smooth pursuit were measured in different eye-in-orbit positions in normal subjects, using a magnetic search coil technique with sinusoidal and step-ramp stimuli. Pursuit also was tested in different horizontal head-on-trunk positions. RESULT...
متن کاملSmooth-pursuit eye-movement deficits with chemical lesions in macaque nucleus reticularis tegmenti pontis.
Anatomic and neuronal recordings suggest that the nucleus reticularis tegmenti pontis (NRTP) of macaques may be a major pontine component of a cortico-ponto-cerebellar pathway that subserves the control of smooth-pursuit eye movements. The existence of such a pathway was implicated by the lack of permanent pursuit impairment after bilateral lesions in the dorsolateral pontine nucleus. To provid...
متن کاملActivation and inactivation of rostral superior colliculus neurons during smooth-pursuit eye movements in monkeys.
Neurons in the intermediate and deep layers of the rostral superior colliculus (SC) of monkeys are active during attentive fixation, small saccades, and smooth-pursuit eye movements. Alterations of SC activity have been shown to alter saccades and fixation, but similar manipulations have not been shown to influence smooth-pursuit eye movements. Therefore we both activated (electrical stimulatio...
متن کاملContextual effects on motion perception and smooth pursuit eye movements.
Smooth pursuit eye movements are continuous, slow rotations of the eyes that allow us to follow the motion of a visual object of interest. These movements are closely related to sensory inputs from the visual motion processing system. To track a moving object in the natural environment, its motion first has to be segregated from the motion signals provided by surrounding stimuli. Here, we revie...
