[ adjective ] (ophthalmology) in or relating to the retina of the eye
Used in print(Nathan Rapport, ""I've Been Here before!"...)
But why is it necessary to reproduce the retinal image within the brain ?
As retinal images are conceded to be an integral function of the brain it seems logical to suppose that the nerves , between the inner brain and the eyes , carry the direct drive for cooperation from the various brain centers - rather_than to theorize on the transmission of an image which is already in required location .
Hereby , the external object viewed by the eyes remains the thing that is seen , not the retinal image , the purpose of which would be to achieve perceptive cooperation by stirring sympathetic impulses in the other sensory centers , motor tensions , associated word symbols , and consciousness .
