MOTOR IMPRESSIONS 173 



bodily activities. All this has demanded cortical repre- 

 sentation in the developing neopallium, and has effected 

 a translation (in which probably the principle of ncuro- 

 biotaxis is involved) of the motor centres from a basal 

 ganglionic mass into the kingesthetic, or pictured, move- 

 ment area. So far as I know, no human being, be he 

 anatomist, physiologist, or clinician, has yet conceived so 

 concrete a picture of the visceral movements involved 

 in respiration, circulation, and the processes of alimenta- 

 tion, carried out in his own body, as to insure these 

 movements a representation in his own cerebral cortex. 

 And it is well that it is not so, for in that case the physi- 

 cian's attendance would be in more frequent demand, 

 and hemiplegia would be inevitably fatal.
