Conclusions

  1. 1.

    Values of the threshold and amplitude of the action potential may differ for different stimuli and the excitability of a neuron is lower for stimuli which, in the given experimental situation, are biologically less important.

  2. 2.

    The efficiency of a synapse depends on the combination of simultaneously activated synapses to which it belongs, and its efficiency rises during processing of stimuli which, at that given moment, are biologically more important.

  3. 3.

    A hypothesis is put forward to explain the ability of a neuron to assess the biological importance of a stimulus and, depending on that assessment, to regulate the electrogenic and chemical properties of its membrane.
