Gamma Oscillations Facilitate Effective Learning in Excitatory-Inhibitory Balanced Neural Circuits.

摘要: Gamma oscillation in neural circuits is believed to associate with effective learning the brain, while underlying mechanism unclear. This paper aims study how spike-timing-dependent plasticity (STDP), a typical of learning, its interaction gamma circuits, shapes network dynamics properties and structure formation. We an excitatory-inhibitory (E-I) integrate-and-fire neuronal triplet STDP, heterosynaptic plasticity, transmitter-induced plasticity. Our results show that performance diverse different synchronization levels. find beneficial synaptic potentiation among stimulated neurons by forming special where sum excitatory input strength correlated inhibitory strength. The circuit can maintain E-I balanced on average, whereas balance temporal broken during learning-induced oscillations. reveals potential about benefits biological circuits.
