N2 - We develop an oscillator model of selective attention based on spread spectrum communication. Stimulus intensity and attention are differentially encoded in the time average of phase velocities of sender oscillators and their temporal structure respectively. Receiver oscillators are driven by a mixture of phase velocities of the sender oscillators. With the aid of top-down modulatory signals that do not change the mean rotational velocity of sender oscillators, our proposed communication scheme allows the receiver oscillators to selectively correlate their velocity with the attended stimulus.
