Synopsis
This is the most important book on sensation to appear for many years. In its search for first principles and its exposition of the mode of action of sensory nerve endings it is as clear and as readable as Adrian's Mechanism of Nervous Action. In the discussion on sensory cortical functions it is as penetrating as Adrian's Physical Basis of Perception. And yet the book as a whole belongs almost to a different world from Adrian's slim volumes. They were both largely accounts of individual pioneer work, while Granit's book draws heavily on the contributions made by workers in Stockholm, in the U.S., in Japan, and in this country. The author's own work on the retina forms one of the most substantial if perhaps not the most clearly expressed parts of the book. His work on the muscle spindle and the a and y motor efferent discharge is the clearest exposition of the sources of one of the newer ideas in sensory physiology, the modification of receptor sensitivity by the nervous system. The application of this idea to the retina may well solve the puzzle of the efferent fibres in the optic nerve. There are, of course, places where the author is still fascinating but not wholly convincing. The logarithmic relation between stimulus and frequency of discharge has been established for retinal receptors and one rather narrow aspect of the discharge for the frog's muscle spindle. There is no reason to believe that the same relation holds for lung and carotid sinus stretch receptors to take two much investigated examples. The names, nuclear bag and myotube endings, provide some terminological exactitude in a confused field, but the evidence for the reflex function of the myotube endings, and even the effect of y efferent discharge on them, is not yet clear enough to allow a full account of the complexities of the simple stretch reflex.Perhaps the chief charm of the book is its mellow discrimination...
