我们研究了皮层神经元对周期性调制的突触刺激反应的可靠性。两种不同类型的皮层神经元的简单地图为基础的模型构建复制的内在共振的可靠性实验数据中发现，并探讨这些共振特性的集体行为的影响，在一个皮层网络模型包含兴奋性和抑制性细胞。我们表明，网络的相互作用可以提高可靠的响应的频率范围，后者可以控制突触连接的强度。讨论了可靠性增强的动力学机制。
We study the reliability of cortical neuron responses to periodically modulated synaptic stimuli. Simple map-based models of two different types of cortical neurons are constructed to replicate the intrinsic resonances of reliability found in experimental data and to explore the effects of those resonance properties on collective behavior in a cortical network model containing excitatory and inhibitory cells. We show that network interactions can enhance the frequency range of reliable responses and that the latter can be controlled by the strength of synaptic connections. The underlying dynamical mechanisms of reliability enhancement are discussed.
