Abstract. We suggest a novel design of neuro-computers using the following principles:

When the input is constant or has inappropriate frequencies, the oscillators do not interact due to the same principle used in selective tuning in radio. However, the rhythmic input can force any two oscillators to interact, which we call dynamic connectivity, if the input’s Power spectrum includes the frequency equal to the difference between the frequencies of the oscillators. Thus, the strength and arrangement of connections between the oscillators is not hard-wired, but it is dynamic and can be controlled by the rhythmic input.

There can be many realizations of such oscillatory neuro-computers since there are many mechanisms for producing these oscillatory behaviors. For example, the oscillators could be phase locked loops, VCOs (Voltage Controlled Oscillators), MEMS resonators, Josephson junctions, lasers, macromolecules, etc.

Detailed information is available.
