Rapid escape reflexes in aquatic oligochaetes: variations in design and function of evolutionarily conserved giant fiber systems

Distribution Pattern of γ-amino Butyric Acid Immunoreactive Neural Structures in the Central and Peripheral Nervous System of the Tubificid Worm, Limnodrilus hoffmeisteri

“…In agreement with Zoran & Drewes (1987), no myelin-like sheath was detectable around dorsal giant fibres and the diameter of lateral ones was about five times greater than that of the medial ones in midbody segments ( Fig. 3b-f).…”

Hindsight and Rapid Escape in a Freshwater Oligochaete

“…Although the electrophysiological and behavioral events during responses to photic stimuli appeared indistinguishable from those elicited by mechanosensory stimuli, the timing of escape responses to these two stimulus types differed markedly with respect to onset latency. The latency between a mechanical stimulus and the onset of LGF spiking was usually less than 12 ms, a value comparable to those in other terrestrial and aquatic oligochaetes (Drewes, 1984;Zoran and Drewes. 1987).…”

Detection and selective avoidance of near ultraviolet radiation by an aquatic annelid: the medicinal leech

“…This result implies a high degree of integration of external and proprioceptive inputs similar to that described for the decision to terminate behaviors, swim or crawl (Mesce and Pierce-Shimomura, 2010). Rapid withdrawal has been extensively studied in oligochaetes (Drewes and Fourtner, 1989;Zoran and Drewes, 1987;Zoran et al, 1988). A similar behavior has been well documented in leeches when stimulation is applied to the anterior body (Magni and Pelligrino, 1978).…”
