Ganglia (single: ganglion) are a loosely tangled mass of nervous tissue which have not become specialized for individual functions such as motor skills, touching, feeling, or intelligence. In more primitive central nervous systems ganglia often serve as an inferior substitute for a brain and/or a spine. Animals or plants which have ganglia can confidently be said to feel no pain--reactions to injury are simple reflexes without lasting memory. Therefore concerns about humane treatment in the cooking of such animals, e.g. lobsters or snails, are irrelevant.
