Masao Ito proposed a cerebellar learning hypothesis with Marr and Albus in the early 1970s. He suggested that cerebellar flocculus Purkinje cells (PCs), which directly inhibit the vestibular nuclear neurons driving extraocular muscle motor neurons ...

Conjunctival vascular adaptation related to ocular comfort in habitual contact lens wearers.
American journal of ophthalmology-glaucoma, 2020PURPOSE To investigate the bulbar conjunctival vascular responses in habitual contact lens (HCL) and non-contact lens (NCL) wearers after short-term lens wear and their relationships with ocular comfort.

Vergence-dependent adaptation of the vestibulo-ocular reflex
Experimental Brain Research, 2003The gain of the vestibulo-ocular reflex (VOR) normally depends on the distance between the subject and the visual target, but it remains uncertain whether vergence angle can be linked to changes in VOR gain through a process of context-dependent adaptation.

Short-term adaptation of the cervico-ocular reflex
Experimental Brain Research, 2004The cervico-ocular reflex (COR) works in conjunction with the vestibulo-ocular reflex (VOR) and the optokinetic reflex (OKR) in order to prevent visual slip over the retina during head movement. The COR induces eye movements in response to proprioceptive signals from the neck.

Short‐term vestibulo‐ocular adaptation: Influence of context
Otolaryngology–Head and Neck Surgery, 1998A number of mechanisms and strategies are used to help an individual compensate for loss of labyrinthine function. One important example is the ability to produce a preplanned motor response that anticipates the motion of the head and so compensates for it.

Adaptive plasticity in the otolith-ocular reflex
Auris Nasus Larynx, 2003This review focuses on the plasticity in the vestibulo-ocular reflex (VOR), especially in the otolith-ocular reflex (OOR). The VOR is a mechanism for the production of rapid compensatory eye movements during head movements. The VOR is under adaptive control which corrects VOR performance when visual-vestibular mismatch arises during head movements.

Ocular cataract and seawater adaptation in salmonids
Aquaculture, 1987Abstract Formation of ocular cataracts after seawater (SW) exposure of yearling coho salmon has been studied in relation to the parr-smolt transformation. No ocular opacity was observed in fish in fresh water (FW). In February and March, survival rates 12 h after exposure to SW were 11 and 20%, respectively, and cataracts were observed in all ...

Effect of adaptive plasticity of linear vestibulo-ocular reflex upon angular vestibulo-ocular reflex
Auris Nasus Larynx, 2000The vestibulo-ocular reflex (VOR) produces compensatory eye movements during head movements. The VOR consists of the angular VOR and the linear VOR. The VOR is under adaptive control that corrects VOR performance when visual-vestibular mismatch arises during head movements. Most experiments concerning plasticity of the VOR have used the angular VOR. So

The instantaneous training demand drives vestibulo-ocular reflex adaptation
Experimental Brain Research, 2020The vestibulo-ocular reflex (VOR) maintains stable vision during rapid head rotations by rotating the eyes in the opposite direction to the head. The latency between onset of the head rotation and onset of the eye rotation is 5-8 ms in healthy humans. However, VOR latency can be 3-4 times larger in patients treated with intra-tympanic gentamicin.

Simulation of adaptive mechanisms in the vestibulo-ocular reflex
Biological Cybernetics, 1992The vestibulo-ocular reflex (VOR), which stabilizes the eyes in space during head movements, can undergo adaptive modification to maintain retinal stability in response to natural or experimental challenges. A number of models and neural sites have been proposed to account for this adaptation but these do not fully explain how the nervous system can ...
