Sensory and Motor Pathway for Monocular Blur-Driven Accommodation
單眼狀態下模糊驅動之調節的感覺與運動通路
Retinal cones stimulated by defocus.
視網膜錐狀細胞被失焦影像刺激
-->
Summated blur signals transmitted through magnocellular layer of LGN to visual cortex
總合的模糊訊號經由外側膝狀體的magnocellular layer到達大腦的視覺皮質
-->
Summated cortical cell responses formulate sensory blur signals
總合的皮質細胞反應調控感覺的模糊信號
-->
Signal also transmitted to parieto-temporal areas and cerebellum for processing/dissemination
信號同時也傳送到parieto顳區及小腦進行處理與傳播
-->
Supranuclear signal goes on to midbrain/oculomotor nucleus/Edlnger-Westphal nucleus where motor
command formulated
核上的信號進入到中腦/動眼神經核/E-W核內進行運動指令調控
-->
Motor command transmitted to ciliary muscle via oculomotor nerve III, ciliary ganglion, and then
short ciliary nerve
運動指令通過動眼神經，睫狀神經節，然後經由短睫狀神經傳輸到睫狀肌
-->
Change in state of contraction of ciliary muscle
睫狀肌的收縮狀態改變
-->
Crystalline lens deforms to attain in-focus retinal image and clarity of vision
水晶體形狀改變以達到視網膜正確對焦並得到清晰影像
