光谱-时间感受野（STRF）经常被用来描述听觉系统的新频率时间滤波特性，直到被记录的神经元。strf非常依赖刺激，反映了听觉系统中强烈的非线性。本文综述了STRF随刺激类型（音调、噪声、发声）、声级和光谱-时间声密度的变化。本文还简要回顾了任务和注意力对STRF形状的影响。讨论了解释这些变化的模型、STRF分析的潜在改进以及对神经编码的影响。(C) 2010 Elsevier B.V.版权所有
The spectro-temporal receptive field (STRF) is frequently used to characterize the Anew-frequency time filter properties of the auditory system up to the neuron recorded from. STRFs are extremely stimulus dependent, reflecting the strong non-linearities in the auditory system. Changes in the STRF with stimulus type (tonal, noise-like, vocalizations), sound level and spectro-temporal sound density are reviewed here. Effects on STRF shape of task and attention are also briefly reviewed. Models to account for these changes, potential improvements to STRF analysis, and implications for neural coding are discussed.
