The latest data on the representation ot vegetative tunctions in the 

 cerebral cortex once more emphasize the importance of precisely the verti- 

 cal plan in the structure of the effector complex ot excitations in the condi- 

 tioned reflex. I am referrnig primarily to Papez's view of the 'visceral 

 cortex' and to the studies of a number of other authors directed towards 

 the same aspect of the subject (Papez, ips.S; Maclean, 1954; Bard, 194^"^; 

 Green, 1958; Adcy, 1958). 



On the basis of authentic facts indicating representation of vegetative
