The predatory sea-slug Pleurobranchaea californica has a simple, accessible nervous system and exhibits a repertory of simple behavioral elements that constitute effective foraging strategies. In this thesis, we introduce initial findings of sensory neurons identified through intracellular staining and electrophysiology, potentially linked to central sensory processing in the Pleurobranchaea.
