[RNA synthesis in giant mollusk neurons following generation of action potentials in response to direct stimulation].
With the aid of autoradiographic and microelectrode methods, it was shown in vitro that the H3-uridine incorporation in the giant neuron decreased during generation of AP. Relationship between the changes of RNA synthesis in the neuron and the number of APs generated by the cell was nonlinear. The same character of the changes in RNA synthesis was shown elsewhere during stimulation via the nerve and generation by neuron of antidromic and ortodromic APs. The data obtained can be regarded as the evidence corroborating regulation of RNA synthesis in the neuron by activity of electro- and chemoexcitable membrane of the cell.
