GIANT NEURONS OF VISCERAL GANGLION OF APLYSIA 235 



Fig. 2. Two giant nerve cells giving off axons toward the neuropile on the right, 

 surface of the ganglion to the left. Note the difference in stain and texture between 

 axoplasm and cytoplasm of the soma, lobulated nucleus and especially the 

 connective tissue invasion of the axon hillock region, forming islands in the 

 lower cell. Calibration: 100 micra. 



Fig. 3. The giant cell somata on the right exhibit abundant glial invasions deep 



in the cytoplasm — all the pale staining wisps. The cells in the center show pigment 



concentrations. Above, a cross section of a nerve at its origin. Giant axons in 



neuropile at the left. Calibration: 100 micra.
