MAUTHNER’S CELL 127 
Gl.b 
Fig. 12 The detail of the axone cap and of the pericellular net of Mauthner’s 
cell drawn from a single section of the same brain as figure 10, but taken from the 
left Mauthner’s cell, Zeiss 1.5 mm. apo., oc. 4, reduced to 788 diameters. The 
section cuts the base of the axone hillock obliquely and to one side of the nucleus. 
The axone cap is shown to be made up of collaterals of nerve fibers, dendrites 
of Mauthner’s cell (C.Dend.) and processes of gla cells (Gl.).. There is no indi- 
cation of the fusion of nerve fibers in the dense neuropil.
