title: [Effect of 6-hydroxydopamine on the electrical characteristics of snail neurons in long-term sensitization].
abstract: Studies of the influence of neurotoxin 6-hydroxydopamine selectively destroying the catecholamine terminals on long-term sensitization, and the role of dopamine in manifestation of characteristics of a membrane of identified neurons during elaboration of plasticity, were fulfilled. Injection of saline was used as the control. It is shown that preliminary injection of 6-hydroxydopamine reduces duration of long-term sensitization, but does not block it completely. It was shown that injection of 6-hydroxydopamine prevents diminishing of membrane and threshold potentials in withdrawal interneurons during formation of long-term sensitization. The experiments demonstrate that shift of electrical characteristics of withdrawal interneurons caused by injection of neurotoxin 6-hydroxydopamine to both naive snails and sensitized snails, statys during at least 10 days.
