SUMMARY. 



The galvanogram of Man displaj's with a low degree of conscious- 

 ness, oscillations which run parallel to respiration and are very likely 

 connected with the respiratory oscillati'ons in the condition of balance 

 in the involuntary nervous system, as these oscillations disappear 

 with preoccupation and as they are not influenced by the involuntary 

 respiratory movements of the arms and are not the outcome of the 

 modifications in the bloodfilling of the extremities, from which the 

 current is derived. 



From the Laboratory for Psychiatry 

 June 1922. of the Groningen University.
