Anticipation is a strategy used by neural fields to compensate for transmission and processing delays during the tracking of dynamical information and can be achieved by slow, localized, inhibitory feedback mechanisms such as short-term synaptic depression, spike-frequency adaptation, or inhibitory feedback from other layers. Based on the translational symmetry of the mobile network states, we derive generic fluctuation-response relations, providing unified predictions that link their tracking behaviors in the presence of external stimuli to the intrinsic dynamics of the neural fields in their absence.
预期是神经场在跟踪动态信息时用于补偿传输和处理延迟的一种策略,并且可以通过缓慢、局部的抑制性反馈机制来实现,例如短期突触抑制、脉冲频率适应或来自其他层的抑制性反馈。基于移动网络状态的平移对称性,我们推导出通用的涨落 - 响应关系,提供统一的预测,将它们在存在外部刺激时的跟踪行为与不存在外部刺激时神经场的内在动力学联系起来。
