shrinkage of the area of sensory loss 10 days after the operation. Only if at least two to
three adjacent posterior roots are resected in man will a permanent sensory loss result.
However, in later stages following resection of several posterior roots, the difference
between the extent of the areas of anaesthesia and analgesia may be less distinct, as I
sometimes found in man. Fig. 116 demonstrates the residual sensory loss following
resection of C2 to C4 posterior roots which I carried out in a case of torticollis spasticus.
The area of analgesia in this case was found to be larger only over the vortex of the skull
and back of the shoulder.
The body image
In connection with the disturbances of sensibility, the body image may be discussed.
The presentation of the body to consciousness and the relationship of one part to another,
known as body scheme (Schilder), body image, postural scheme (Head), 1'image de
notre corps (PHermitte), is constantly reinforced by afferent impulses from all parts of
the body, including labyrinth and visual impulses. While disturbances of the body image
in cerebral lesion, especially of the parietal lobe and thalamus, are frequent and have been
widely discussed in the neurological literature (Head & Holmes, 1920; Gerstman, 1924;
