This described it as a resonator or an integrator; if the rest state disappears through Andronov-Hopf, then the neuron behaves as the former and selects multiples of its eigenfrequency
in afferent signals in "choosing" whether to fire.
analysis was implemented using structural mechanics, dynamics, and vibration modules.
We assume a constant frequency of 0.34 Hz, which is close to the first eigenfrequency
of 0.354 Hz.
The use of a difference between the two frequencies matching a structural eigenfrequency
determines a relevant response, as indicated in the literature .
The first (a) at eigenfrequency
4486 Hz, the second (b) and the third (c) at 9389 Hz and 13855 Hz accordingly.
and Runyan (1965)  provide indirect evidence of the existence of such a relationship for the eigenfrequency
mode n = 1.
For discrete linear system, the condition for stability is h [less than or equal to] 2/[[omega].sup.mos.sub.max], where [[omega].sup.mos.sub.max] is the highest circular eigenfrequency
of the system.
