[The electrical activity of retinal ganglion cells according to central blood pressure (author's transl)].

Recording of single fiber activity of the N. opticus represents an objective electrophysiological method for investigation of the function of the retina. The relationship between retinal function and blood pressure was explored in cats and it was discovered that the autoregulation of the eye secures normal retinal functioning even in the presence of considerable variations in central blood pressure. With cats this ranges between 60 and 140 mm Hg average pressure in the A. carotis communis.
