The peripheral retinal 'map'.
The condition of the periphery of the retinal field of the human eye is of considerable significance, it is suggested, to those participating in various sporting activities.  Its boundaries shrink and expand depending upon the physiological conditions imposed both upon the eye and upon the organism as a whole.  Consequently its message to the brain may be impaired under stress with resulting danger owing to delayed response.
