Our visual system has many interesting abilities like vestibulo-ocular reflex. These abilities are helpful for us to perceive the environment effectively and often have adaptability to the environment. On the other way, LSSI (Local Sensory Signals Integration) learning base on the smoothness of the relation between the spatial and temporal information, has been already proposed. In this paper, ...

BACKGROUND The American Academy of Pediatrics recently published recommendations for the red reflex assessment in the newborn period to detect and treat ocular disorders as early as possible, and to prevent lifelong visual impairment and even save lives. The test is technically simple to perform, non-invasive, requires minimal equipment and can detect a variety of ocular pathologies including c...

Cerebellar long-term depression (LTD) is a model system for neuronal information storage that has an absolute requirement for activation of protein kinase C (PKC). It has been claimed to underlie several forms of cerebellar motor learning. Previous studies using various knockout mice (mGluR1, GluRdelta2, glial fibrillary acidic protein) have supported this claim; however, this work has suffered...

INTRODUCTION Based on the knowledge that traumatic brainstem damage often leads to alteration in brainstem functions, including the vestibulo-ocular reflex, the present study is designed to determine whether prediction of outcome in the early phase after severe traumatic brain injury is possible by means of vestibulo-ocular monitoring. METHODS Vestibulo-ocular monitoring is based on video-ocu...

BACKGROUND Skew deviation is typically caused by brainstem damage, and has not been identified with focal cerebellar lesions. This vertical strabismus has been attributed to asymmetric disruption of vestibuloocular reflex (VOR) projections from otolithic receptors of the utricle to ocular motoneurons, but asymmetry of the utriculo-ocular counter-roll reflex has not been detected. METHODS Lesi...

The present study was aimed at evaluating the alterations in the human reflexes brought about by briefly altered ventilations. In 20 healthy young male volunteers, the H reflex and blink reflex were studied during normal ventilation, voluntary hypoventilation and voluntary hyperventilation. The latencies of these reflexes were compared. It was observed that the amount of altered ventilations us...

The purpose of this study was to determine whether significant attentional resources are required to accurately monitor changes in bodily orientation, using vestibular information. This question was addressed firstly using a dual-task paradigm in which orientation perception tasks and a speeded auditory tone discrimination task were carried out either singly or in combination. For the active or...

This paper is part of a study of gaze control for a two-eyed robot head. The kinematics of the head and eye movement planning for the subcontrols loosely corresponding to saccade, pursuit, VOR(vestibulo-ocular reflex), OKR(optokinetic reflex), and vergence are presented.
