EFFECT OF OVER-ACTIVITY ON SYNAPSE

The above described findings were repeated in a different inten- 

 sity in many cases of fatigue by means of Levaditi's method, 

 although there were several cases with negative findings in the 

 synapse. It must be emphasized here that in the resting control 

 animal the pericellular reticular structure was always brought out 

 clearly and sharply. Of the manifestations of the glia cells in the 

 synapse I shall give a more precise description later. As espe-

cially worthy of note here, I want to discuss the relation between 

 the glia cells and the reticular glia structure. The protoplasm 

 and the protoplasmatic processes of the neuroglia cells increase 

 and swell in mass, as will be mentioned below. Some processes 

 show their relation to the reticulum even in their swollen condi- 

 tion, but some of the processes are no longer connected with the 

 glia reticulum. Some of them fall to pieces so that we find pro- 

 toplasm masses of different shape and size around the glia cells.
