...most accurate measurements ever made of the manner in which the optic nerve transmits nerve impulses from the eyes to the brain have been made recently at the laboratories of the Medical School and have thrown new light on the laws governing the mechanism of vision...
Studying the mechanism of vision with this extraordinarily delicate machine, the experimenters found that the curves which had been roughly measured by previous investigators could be plotted with much more accuracy. They discovered that the smoothness and regularly of these curves are disturbed by a large number of small oscillations, and that these oscillations have to do with the perception of color...
...measure coughly the intensity of this electrical impulse. They have represented its intensity by a curve, and have found that when a light is flashed upon the eye, the curve rises sharply, then dips, and then rises again gradually. This second rise corresponds with the phenomenon known as after-vision", which may be noticed by anyone who looks at a bright light and then closed his eyes. He continues to "see" the light, because the optic nerve is still transmitting impulses to the brain...
...frog's eye, proved far more sensitive to light than any hitherto constructed, showing that the eye is a more sensitive instrument than any which it has been possible for man to construct. It measured the impulse from light a great deal too faint for ordinary human vision. The galvanometer, for instance, registered a stimulus from the light, as faint as would be that of a candle set 1200 feet away from the frog's eye, and did this, furthermore, with the front of the frog's eyeball cut off so that there was no lens to collect the diffused...
...foundation course" in the college is not a new one. Just such are Economics A, English 41, and all of the elementary courses; but English A--as Mr. Gavit states, it is handicapped by that name--is a course more elementary in that it is more fundamental. The vision that it can give, and the faculties that it can develop, make it a necessary preliminary to all study. "It affords the framework and warp into which all the rest of his college and postgraduate work and intellectual acquisitions of his after life may be built and interwoven...
