system of gastropods consists of a series of paired ganglia
connected by major nerve cords, and a number of smaller
branching nerves.  General layout of the gastropod ganglia. In
most species, the brain is fused into a single, six-lobed, organ
Buccal ganglia of Aplysia californica.  The brain of a gastropod
consists of three pairs of ganglia, all located close to the
oesophagus. In some primitive forms, these ganglia are
relatively discrete, but in most species they have become so
closely bound together as to effectively form separate lobes of
a single structure.  The cerebral ganglia are located above the
oesophagus and supply nerves to the eyes, tentacl
