title: A source of large axons for neurophysiology: the North Atlantic squid Illex illecebrosus.
abstract: A new axon preparation from the ommastrephid squid (Illex illecebrosusus (Lesueur)) is described. This squid is common in the Northwestern Atlantic and features a number of long, unbranched, and moderately large-diameter axons having no apparent 'twigging.' Although the diameters of these axons are somewhat smaller than those of 'giant' axons coming from some other species of squid, this axon preparation should be considered as an attractive alternative for neurobiologic research.
