摘要: 1. Activity in the three known conduction systems Calliactis parasitica (nerve net, SS 1, 2) has been monitored for periods up to 2 h. 2. The ectodermal slow system (SS 1) shows irregular activity and many of observed spontaneous pulses may fact result from undetected external stimuli. 3. rhythmic changes frequency (approximate range 0.2-7.5 pulses/min.) 4. During low-frequency a short (up 10 pulses), high-frequency 15/min) burst through-conducting nerve net is seen. A contraction sphincter muscle often seen after burst.
