[Effect of theophylline on electrical activity of the bursting type in an identified edible snail neuron].
Effect of the theophylline was studied on the electrical activity of the Helix pomatia bursting neuron RPal. It is found that 1 mM/l theophylline induces an increase of the membrane potential wave amplitude, the duration of the burst of the action potentials, its frequency, number and interburst period. 2.5 and 5 mM theophylline leads to inhibition of the bursting activity. The possible role of the cyclase system of the neuron in regulation of the electrical activity is discussed.
