Recent developments in earthworm neurobiology

Organization of the sensory system of the earthworm Lumbricus terrestris (Annelida, Clitellata) visualized by DiI

“…Variation of the pattern of primary sensory cells could be determined by the number of segmental nerves of VNC ganglia and different environmental stimuli. Our results support the earlier hypotheses that the basiepidermal plexus consists of sensory and motor fibers, and it could mediate local reflexes of the body wall (Smallwood,1926; Miller and Ting,1949; Mill,1978, 1982), however, to reveal the function of this system further physiological, pharmacological, and synaptological studies are necessary.…”

External sense receptors in microdrile oligochaetes (Annelida, Clitellata) as revealed by scanning electron microscopy: Typology and patterns of distribution in the main taxonomic groups

“…At first glance, the typology and distribution of the external ciliate receptors in microdriles is similar to that reported for the other clitellates (Knapp and Mill, 1971; Moment and Johnson, 1979; Jamieson, 1981; Farnesi et al, 1982; Mill, 1982; Sawyer, 1986; Fernández et al, 1992). The same basic categories of ciliate sensory cells (penetrative uniciliate and/or penetrative multiciliate) appear to be involved in the composition of these receptors.…”

Hindsight and Rapid Escape in a Freshwater Oligochaete

“…8E). These two ciliated cell types are nearly identical to the proposed epithelial mechanoreceptors described in the anterior segments of earthworms (Knapp and Mill, 1971;Mill, 1982) and an aquatic oligochaete, Rhynchelmis liniosella (Moritz and Storch. 1971).…”
