[Circahoralian rhythms and integrative function of neurons]

The neuron's integrative function is directly related to circumhoralian rhythms of energy and plastic processes in the neuron's soma. The neuron's excitability and its integral reaction to a test stimulus are determined by the energy-dependent accumulation of calcium ions and decreased aggregation of tigroid and mitochondria, as well as by changes in the soma and axon hill geometry. Upon synchronization of functional load and energy of the cell, an increased excitability of the neuron and formation of a temporal relationship are possible.
