Criteria for the appearance of post-tetanic potentiation of transmission at central synapses in Helix aspersa.
Long-lasting potentiation of inhibitory post-synaptic potentials occurs at 2 identifiable synapses in Helix brain. It appears only after tetanic stimulation and after a minimum of 20 impulses. Its amplitude and duration depends on the number of stimuli.
