[Presynaptic mechanisms of synchronizing fluctuations in the amplitude of synaptic potentials in the central nervous system of Helix lucorum taurica L].
The amplitude of EPSP arising in different command neurons (LPa2, LPa3 and PPa3) of the snail Helix lucorum after stimulation of presynaptic element LPa7 fluctuated synchronously. Synchronous application of acetylcholine on two command neurons showed that synchronous EPSP fluctuations were connected not with postsynaptic but with presynaptic mechanisms. The existence of a special modulating neuron is suggested.
