Chronic administration of caffeine to common snails increased the rate of formation of a conditioned defensive reflex. When daily caffeine injections were given immediately after the training procedure, the conditioned defensive reflex was acquired more quickly than when caffeine injections were given before the training procedure started. Chronic caffeine(More)
Studies of electrical characteristics of command neurons of the defensive reflex have shown that membrane potential does not reliable differ for both naive and learned snails with changing of the calcium concentrations in external solution. With increasing of the concentrations of calcium ions it is observed the increases of threshold potential from 14 +(More)
Antibodies against calcium-binding protein S100 (AB-S100) 1.5-fold increased, while quinine 2-fold decreased the frequency of action potential generation in B4 and B6 neurons. Application of quinine against the background of AB-S100 treatment returned this parameter to the initial level. Pretreatment with AB-S100 in low doses prevents changes the frequency(More)
Electrophysiological experiments showed that chronic administration of neuroleptic chlorpromazine depolarized plasma membrane and decreased the threshold of action potential generation in command neuron of defense behavior of edible snail and motoneurons of pneumostome closure reflex. The effects of chlorpromazine on electrical parameters of the identified(More)
Studies of the electrical characteristics of the command neurons of a defensive reflex showed that the membrane potential showed no significant changes in response to changes in the calcium concentration in the perfusing solution in either intact or trained snails. Increases in the calcium ion concentration in intact snails were accompanied by increases in(More)
It was found that chronic injection of caffeine to grape snail increases a velocity of elaboration of conditioned defensive reflex. It was shown that after daily injection of caffeine immediately after procedure of learning the conditioned defensive reflex elaborated faster than daily injection before procedure of learning. It has been shown, that chronic(More)
