Not illustrated. 1879 edition. Excerpt: ...brain in cases of amputation or arrested development of the lower extremity, with the expectation of finding atrophy of the corresponding centre in accordance with Luys' views. Whether these expectations are altogether justifiable may be questioned. For my own part I should on theoretical grounds regard this as highly improbable, except in cases of congenital deficiency. Mere absence of a limb after it has been for a long time in full functional activity, would not, I think, induce perceptible atrophy in the cortical motor centres. For mere objective or actual movement is not the only function of these centres. Being also the organic registers of the memory of their corresponding movements, and the basis of motor ideation, it is, I think, possible that their nutrition may be maintained notwithstanding the cessation of their activity in the innervation of actual or objective movement. But, theoretical considerations apart, the practical difficulties in the way of a satisfactory solution of this problem are very great, and I do not think that, up to the present at least, they have been disposed of successfully. An important communication on this subject was recently presented to the Societe de Biologie (January 5, 1878), by M. Fere, well known for his valuable researches in cerebral topography. M. Fere argues that neither the method of ascertaining the existence of atrophy, by comparing the relative size of homologous convolutions in each hemisphere, nor that founded on the advance or recession of the fissure of Eolando, round which the motor centres are grouped, is reliable; inasmuch as in the perfectly normal brain there are great variations and asymmetry in the convolutions and fissures in the two hemispheres, and there is no absolutely more
