Conclusion

  1. 1.

    During the recording of total ionic currents in different areas of the somatic membrane, significant inhomogeneities are noted in them.

  2. 2.

    The investigation of local ionic transmembrane currents during the effect on the cell of external influences revealed the possibility of their rapid reorganization, which, as is the case with the heterogeneity in chemical sensitivity, may speak in favor of hypotheses concerning the possibility of selective functional transformation of various areas of the cell.

  3. 3.

    A local increase in the entering currents is observed at the first stage of the multidirectional changes in the reorganization of the response of the neuron.

  4. 4.

    The use of the experimental model described in the study makes it possible by acting on a non-specialized, limited area of the somatic membrane, to form specific reorganizations of the electrical response of the cell, and, by using the accessibility of these active zones, to investigate the cellular mechanisms of plastic reactions.
