Abstract

It has been hypothesized that sensory feedback is a critical component in determining the functionality of a central pattern generator. To test this, Yu and Thomas's recent work Yu and Thomas (Biol Cybern 115(2):135-160, 2021) built a model of a half-center oscillator coupled to a simple muscular model with sensory feedback. They showed that sensory feedback increases robustness against external noise, while simultaneously expanding the potential repertoire of functions the half-center oscillator can perform. However, they show that this comes at the cost of robustness against internal noise.

感官反馈扩大了动态复杂性，并有助于对噪声的鲁棒性。

据推测，感觉反馈是决定中枢模式发生器功能的关键组成部分。为了验证这一点，Yu和Thomas (Biol Cybern 115(2):135- 160,2021)建立了一个半中心振荡器模型，该模型与一个具有感官反馈的简单肌肉模型耦合。他们表明，感觉反馈增加了对外部噪声的鲁棒性，同时扩展了半中心振荡器可以执行的潜在功能。然而，他们表明，这是以对内部噪声的鲁棒性为代价的。

期刊介绍： Biological Cybernetics is an interdisciplinary medium for theoretical and application-oriented aspects of information processing in organisms, including sensory, motor, cognitive, and ecological phenomena. Topics covered include: mathematical modeling of biological systems; computational, theoretical or engineering studies with relevance for understanding biological information processing; and artificial implementation of biological information processing and self-organizing principles. Under the main aspects of performance and function of systems, emphasis is laid on communication between life sciences and technical/theoretical disciplines.
