Voltammetric measurement of oxygen in single neurons using platinized carbon ring electrodes.

Abstract

Naflon-coated ultrasmall platinum ring electrodes have been implanted in the giant dopamine neuron of the pond snail Planorbis corneus, and the oxygen concentration inside these single neurons has been estimated. Experimental data suggest that the intracellular oxygen level in the identified dopamine neuron of P. corneus is approximately 0.032 mM. The… (More)
