The Cell Body (which is sometimes referred to as a soma, perikaryon, or cyton) is the large bulbous part of a neuron, which contains the cell nucleus as well as most of the other organelles in a neuron. Because it has most of the organelles, most of the proteins are synthesized in the cell body. For the purpose of Retinal Connectomics, the cell body is generally uninformative, except on rare occasions, the cell body is the postsynaptic terminal in a synapse. As well as having the nucleus, the dendrites and usually an axon also branch off of the cell body.

In EyeWire the cell bodies are often frozen because they take a lot of time to trace, are uninformative, and the AI (Artificial Intelligence) has trouble with them, since it's designed for dendrites.
