The physiologist should read it, since it illuminates a few clinical problems toward the solution of which many are striving, possibly unaware of the eventual application of their own minutiae.

The main theme of the book can be most readily illustrated by the quotation of a paragraph:

Afferent impulses from this 'trigger point' eventually create an abnormal state of activity in the internuncial neuron centers of the spinal cord gray matter. The internuncial disturbance in turn is reflected in an abnormal motor response from both the
