Essentially, this book attempts to apply the nomenclature of electronic regulatory mechanisms to the physiologic control of willed motion and of the circulation. The principles of feedback and servomechanisms in technique are considered. They are then discussed in detail in relation to reflex and orderly volitional activity of striated muscles. The role of muscle spindles and tendon organs, for example, is treated as a feedback to anterior horn cells and higher motor centers. Similarly, the author deals with the problems of control of blood pressure, of peripheral blood flow, and of cardiac activity.
The author believes that he clarifies and explains physiologic data. I can not share this enthusiasm and have gained little by carefully studying the 210 pages of this book.
The writing is in an exceptionally complicated German. It is unusual to call muscle spindles "dilator receptors." There are other minor abuses of English terms. However those who
