[The central neurons that inhibit the work of the heart in the edible snail].
The neurones causing the inhibitory postsynaptic potentials (IPSP) with duration 150-200 ms in the myocardium have been identified in the visceral ganglion of Helix pomatia. The neurones are characterized by the high frequency of discharges (2-3 c/s) which changes modulate the heart frequency. IPSP is blocked by d-tubocurarine in the concentration 5.10(-5)-1.10(-4) M.
