[Quasielectrostatic manipulation of a single neuron: trace phenomena and comparison with intracellular excitation].

The investigation of quasielectrostatic impact (QESI) on the electrical activity of an isolated neuron of the mollusc brain was continued under conditions of continuous (20 min to 2 hours) and repeated applications. It was shown that the repeated application of QESI changes the level of electrical activity of the neurons. For different cells the repeated application of QESI produces an increase as well as a decrease of the neurons activity, while the thresholds of the frequency modulation of the spontaneously active and the excitation of the "silent" cells become lower.

[Quasielectrostatic impact on individual neurons: frequency modulation of activity and excitation].

The quasielectrostatic impact (QESI) on the electrical activity of an isolated neuron of mollusc was investigated. It was shown that QESI with the frequencies of (0.05--1) Hz controls the time pattern of the nerve cell electrical activity, producing the frequency modulation (FM) of action potentials (AP) in accordance with the frequency and field intensity applied.
