title: [Interrelationship between grape snail alimentary and defense behavior command neurons].
abstract: Food stimulus (carrot juice), releasing feeding behaviour in intact snails, evoked spike discharges in giant meta-erebral cells (considered to be command neurones of feeding behaviour) and subthreshold EPSPs in giant parietal cells (command neurones of avoidance behaviour) of a half-intact preparation. Tactile stimulation, eliciting avoidance reactions in intact snails, evoked hyperpolarization in command neurones of feeding behaviour and a spike discharge in command neurones of avoidance behaviour. Spikes induced into either of command neurones produced no changes in activity of other command cells. Inhibition of command neurones of feeding behaviour is assumed to be the basis of behavioural choice when food and tactile stimulus are presented simultaneously.
