Abstract

The effect of amtizol, a blocker of the inactivation of calcium-dependent potassium channels of the outward current, on the spontaneous and evoked impulse activity of these cells was investigated in experiments on Retzius neurons of the leech. It was demonstrated that the extracellular application of amtizol induces a decrease in the amplitude and an increase in the duration of evoked AP, while not exerting a perceptible influence on the form of the spontaneous AP. In addition, disruption of the development of the process of habituation that develops in the norm during high-frequency synaptic activation of the neuron is observed in a solution containing amtizol.
