Pharmacological actions of essential (zinc, copper) and toxic metal ions (lead, mercury) on neurons and neuronal synapses of the snail, Helix pomatia L.

Abstract

Actions of zinc, copper, lead and mercury ions on identified neurons and neuronal synapses of the snail, Helix pomatia L. were examined by use of electrophysiological methods. The studied metal ions depolarized the membrane and decreased the resistance but the neuronal excitability changed differentially. Copper and zinc transiently increased the amplitude… (More)
