  2. The axoplasm can be extruded, thus allowing studies of its composition.
  3. Large synapses between giant nerve cells make them easy to study.
  4. Giant ion channels allow for the insertion of recording electrodes into the channels.
  5. Properties of the squid's axons and synapses can be related to its behavior
