[Local changes in the transmembrane ion currents in plastic reorganization of electrogenesis in isolated neurons of the pond snail].
Transmembrane ion currents were studied on limited (pore diameter 6-15 mcm) areas of isolated neurone's soma membrane. The significant differences of the amplitude and correlation of input and output currents of various areas of the cell membrane were observed. The different directions of transmembrane ion currents' local changes were recorded only in the site of action stimulus during the formation of plastic changes of neurone responses. Natural heterogeneity of total ion current of cell membrane, rapid changes of current components values at local influences probably testify to the possibility of selective plasticity of separate neurone areas.
