Learning to synchronize: How biological agents can couple neural task modules for dealing with the stability-plasticity dilemma

A: The pMFC. In the pMFC, the phase code neurons oscillate at a 5 Hz frequency. The rate code neuron of the pMFC gives bursts to the Processing unit. Every time the E-neuron reaches a high amplitude, the probability of a burst becomes high. B: E-neurons of the Processing unit. In the Processing unit, the phase code neurons oscillate at a faster gamma-frequency. It is illustrated how a burst leads to (de)synchronization of oscillations that at first were not (de)synchronized. C: Rate code neurons in the Processing unit. Consequences of synchronization between the phase code neurons can be observed in the rate code neurons. At first, only the neuron of layer 1 is activated because it receives a constant external input signal. Importantly, this activation is modulated by G(Ei) in Eq (4). As a consequence, as long as the E-neurons are not synchronized, communication between the corresponding rate code neurons is very inefficient; but when the E-neurons are synchronized, communication between the corresponding rate code neurons is efficient.
