Abstract
1. Activity in the three known conduction systems in Calliactis parasitica (nerve net, SS 1, SS 2) has been monitored for periods up to 2 h. 2. The ectodermal slow system (SS 1) shows irregular activity and many of the observed spontaneous pulses may in fact result from undetected external stimuli. 3. The SS 2 shows rhythmic changes in frequency (approximate range 0.2-7.5 pulses/min.) 4. During periods of low-frequency SS 2 activity a short (up to 10 pulses), high-frequency (up to 15/min) burst of activity in the through-conducting nerve net is seen. A slow contraction of the sphincter muscle is often seen after a nerve net burst.This publication has 28 references indexed in Scilit:
