Abstract

Noise is generally considered to be detrimental. In the right conditions, however, noise can improve signal detection or information transmission. This counterintuitive phenomenon is called stochastic resonance (SR). SR has generated significant interdisciplinary interest, particularly in physics, engineering, and medical and environmental sciences. In this review, we discuss a growing empirical literature that suggests that noise at the right intensity may improve the detection and processing of auditory, sensorimotor, and visual stimuli. We focus particularly on applications of SR in sensory biology and investigate whether SR-based technologies present a pathway to improve outcomes for individuals living with sensory impairments. We conclude that there is considerable evidence supporting the application of SR in developing sensory prosthetics. However, the progression of SR-based technologies is variable across the sensory modalities. We suggest opportunities for further advancements in each modality, considering the best approaches to maximise benefits and capitalise on progress already made. Overall, SR can offer opportunities to improve existing technologies or to motivate innovations.

感觉系统中的随机共振及其在神经假肢中的应用

噪音通常被认为是有害的。然而，在适当的条件下，噪声可以改善信号检测或信息传输。这种与直觉相反的现象被称为随机共振（SR）。随机共振引起了跨学科的极大兴趣，尤其是在物理学、工程学、医学和环境科学领域。在这篇综述中，我们将讨论越来越多的实证文献，这些文献表明，适当强度的噪声可以改善对听觉、感觉运动和视觉刺激的检测和处理。我们特别关注 SR 在感官生物学中的应用，并研究基于 SR 的技术是否是改善感官障碍患者生活质量的途径。我们的结论是，有大量证据支持将 SR 应用于开发感官假肢。然而，基于 SR 的技术在各种感官模式中的进展各不相同。我们为每种模式的进一步发展提供了机会，同时考虑了实现效益最大化和利用已取得进展的最佳方法。总之，SR 可以为改进现有技术或推动创新提供机会。

期刊介绍： As of January 1999, The journal Electroencephalography and Clinical Neurophysiology, and its two sections Electromyography and Motor Control and Evoked Potentials have amalgamated to become this journal - Clinical Neurophysiology. Clinical Neurophysiology is the official journal of the International Federation of Clinical Neurophysiology, the Brazilian Society of Clinical Neurophysiology, the Czech Society of Clinical Neurophysiology, the Italian Clinical Neurophysiology Society and the International Society of Intraoperative Neurophysiology.The journal is dedicated to fostering research and disseminating information on all aspects of both normal and abnormal functioning of the nervous system. The key aim of the publication is to disseminate scholarly reports on the pathophysiology underlying diseases of the central and peripheral nervous system of human patients. Clinical trials that use neurophysiological measures to document change are encouraged, as are manuscripts reporting data on integrated neuroimaging of central nervous function including, but not limited to, functional MRI, MEG, EEG, PET and other neuroimaging modalities.
