Fig. 5.

The Golgi apparatus is not always associated with the botrysome. Low-power electron micrograph of three neurons (outlined in dotted lines) in layer V of kitten visual cortex. One neuron contains a Cat-307 immunoreactive botrysome (arrowheads) labeled with HRP, located adjacent to a Golgi apparatus (G). The adjacent neuron contains numerous Golgi apparati but no botrysomes. Golgi apparati are much more numerous than botrysomes and can be seen throughout the cell body. The botrysome appears to be associated with a specialized region of the Golgi apparatus located near the base of dendrites. Scale bar, 3 μm.
