Abstract
Astrocytes play a central role in inducing concerted phase synchronized
neural-wave patterns inside the brain. In this article, we demonstrate that
injected radio-frequency signal in underlying heavy metal layer of spin-orbit
torque oscillator neurons mimic the neuron phase synchronization effect
realized by glial cells. Potential application of such phase coupling effects
is illustrated in the context of a temporal "binding problem". We also present
the design of a coupled neuron-synapse-astrocyte network enabled by compact
neuromimetic devices by combining the concepts of local spike-timing dependent
plasticity and astrocyte induced neural phase synchrony.
