Glycine-activated membrane conductance of spinal cord nerve cells of the 6--11-day old chick embryo

Isolated spinal cord neurons of 6-11 day old chick embryos were investigated under conditions of intracellular perfusion and voltage clamp. Glycine-activated chloride conductivity characteristics of neuronal membranes did not change at the investigated stages. Concentrations evoking half-effect (7.5 X 10(-5) mol/l) and Hill's coefficients (1.65-1.95) were also constant at these stages.
