[The cortical layer of the cytoplasm--a possible site of the action of prenervous transmitters].
Specific and opposite effects of some transmitter antagonists (beta-adrenoblockers, serotonin antagonists) on mechanical properties of the surface of fertilized eggs of the sea urchin Paracentrotus lividus have been demonstrated. Possible role of endogenous transmitters in regulation of the properties of cytoplasmic cortex is discussed.
