[The monosynaptic connection: identified synapses in the CNS of the edible snail].
By electrophysiological and microanatomical methods of analysis of snail CNS small neurones it was shown that a number of neurones form a monosynaptic connection (MSC) with the gigantic polyfunctional neurone LPa3. By using cobalt and nickel staining, the structure of MSC cells LPa7--LPa3 was studied. Six identified synapses in two LPa3 processes zones were found. Physiological analysis showed that the revealed MSC was plastic. The described MSC with identified synapses is convenient for studying synaptic transmission mechanisms.
