An explanation for the ipsilateral pathways of the retinal fibers of the binocular vision.","authors":"Jamal A Ghaida,&nbsp;Ayman G Mustafa,&nbsp;Saleh M Banihani","doi":"10.17712/nsj.2015.4.20140620","DOIUrl":"https://doi.org/10.17712/nsj.2015.4.20140620","url":null,"abstract":"In contradiction to the crossing of all retinal fibers in the lateral-eye species, the retinal fibers of binocular vision in frontal-eye species run either ipsilaterally or cross the midline twice to terminate the ipsilateral cerebral hemisphere.1 It is hypothesized that carrying separated information, such as vision in lateral eyes, seems to create the need for functional coordination between the 2 cerebral hemispheres. This coordination appears to be mediated by fiber crossing. Shared information; however, such as binocular vision and olfactory pathway, runs ipsilaterally. In this situation, both cerebral hemispheres receive the same information; therefore, functional coordination between the 2 hemispheres via fiber crossing is mostly unnecessary.1 In another view,2 the eye-forelimb hypothesis suggests that the ipsilateral retinal fibers of binocular vision as the right fibers of the right retina carry binocular vision from the left hemifield of the right visual field and run ipsilaterally to reach the right cerebral hemisphere. The latter controls the left limbs; thus, enabling more target-oriented motor response to stimuli in the left hemispace including the left hemifield of the right visual field. According to the last hypothesis,2 if these described fibers were to cross the midline to the left cerebral hemisphere, the same fibers would have to cross the midline again to the right cerebral hemisphere to control the left limbs. This obviously would elongate the pathway and probably would add at least another synaptic link. Subsequently, this would make the motor response to stimuli in the binocular visual hemifields slower and less effective. Larsson2 noted that in the owl, binocular vision is mediated by long neural pathways with double crossing and more synaptic links, despite rapid and effective motor response to stimuli in the binocular visual hemifields. \u0000 \u0000In this present paper, we propose an alternative hypothesis, ‘ipsilaterality serves contralaterality’, for the explanation of the presence of ipsilateral retinal fibers of binocular vision. This hypothesis relies on the well-documented principle of contralaterality, which dominates the neural pathways in the CNS.1 In this concept, each cerebral hemisphere deals with the contralateral hemispace. For instance, the right cerebral hemisphere receives sensory stimuli from the left hemispace through the right halves of the 2 retinae. The binocular visual fibers; namely, the right fibers of the right retina and the left fibers of the left retina run ipsilaterally to reach the right and the left hemispheres contralateral to their binocular visual hemifields; namely, the left hemifield of the right visual field and the right hemifield of the left visual field. \u0000 \u0000In lateral eyes, such as in birds, the 2 hemifields of the right visual field are located in the right hemispace and all the stimuli from the right visual field reach the left cerebral hemisphere after they cross the midline.
