Short-term adaptive control processes in vergence eye movement
The "Dual Mode" theory for the control of disparity vergence eye movements states that two control components, a preprogrammed "transient" component and a feedback control "sustained component, mediate the motor response. Although prior experimental work has isolated and studied the transient component, little is known of the contribution of the sustained component to vergence response. The tim...
متن کاملPalisade endings in human extraocular muscles.
The presence of nerve terminals in the tendinous insertions of human eye muscles was investigated histologically in adult human eye muscles obtained from donor eyes and in muscle pieces resected from juvenile patients undergoing surgical correction for strabismus. Lateral and medial recti, superior and inferior oblique muscles from adults, were stained "en bloc" using a silver impregnation meth...
متن کاملSpectral Continuity and Eye Vergence Movement
In the Marr-Poggio model of human stereopsis, eye vergence movement is tightly coupled to the matching process. Any local area of any spatial frequency tuned channel can initiate a vergence movement designed to bring zero crossings within that local area into their range of correspondence. Since, in the human system, the resource of eye movement is limited, the control problem inherent in such ...
متن کاملVergence control across saccades in dyslexic adults.
Many aspects of vision have been investigated in developmental dyslexia. Some research suggests deficits in vergence control (e.g. Buzzelli, 1991, Optom. Vision Sci. 68, 842-846), although ability to control vergence across saccades has not yet been investigated. We have explored this question indirectly using Enright's (1996 Vision Res. 36, 307-312.) sequential stereopsis task. The task requir...
متن کاملMolecular characteristics suggest an effector function of palisade endings in extraocular muscles.
PURPOSE To analyze palisade endings in cat extraocular muscles (EOMs) and to clarify whether these EOM-specific organs are sensory or motor. METHODS Twelve cats aged between 1 and 16 years were analyzed. Whole EOM tendons were immunostained using four different combinations of triple fluorescence labeling. Triple labeling included antibodies against choline acetyltransferase (ChAT), neurofila...
