Sensitivity of central auditory neurons to frequency modulated (FM) sound is often characterized based on spectro-temporal receptive field (STRF), which is generated by spike-trigger averaging a random stimulus. Due to the inherent property of time variability in neural response, this method erroneously represents the response jitter as stimulus jitter in(More)
Time variance of sound energy is an important feature of communication signals that include speech [1]. One of the two major components is time variance in frequency or frequency modulation (FM). Substantial numbers of neurons have been found along the ascending auditory pathways responsive to FM but not pure tone stimuli (FM sensitive cells), starting at(More)
To simulate central auditory responses to complex sounds, a computational model was implemented. It consists of a multi-scale classification process, and an artificial neural network composed of two modules of finite impulse response (FIR) neural networks connected to a maximum network. Electrical activities of single auditory neurons were recorded at the(More)
