WebMay 15, 2002 · Our stimuli, the dynamic moving ripple (DMR) and ripple noise (RN), allow us to systematically characterize response attributes with the spectrotemporal receptive field (STRF) methods to a rich and dynamic stimulus ensemble. Theoretically, we expect that STRFs derived with DMR and RN would be identical for a linear integrating neuron, and … WebLifetime exposure to a realistic environmental noise. (a) We designed a broadband sound based on amplitude-modulated dynamic moving ripples (Kowalski et al. 1996; Escabi and Schreiner 2002).A random low-pass temporal envelope was applied to match environmental sounds. The overall spectrum was flat to ensure that no particular frequency band was …
WebNov 1, 1996 · 1. Auditory stimuli referred to as moving ripples are used to characterize the responses of both single and multiple units in the ferret primary auditory cortex. Moving ripples are broadband complex sounds with a sinusoidal spectral profile that drift along the logarithmic frequency axis at a constant velocity. 2. Neuronal responses to moving … WebJun 20, 2012 · Dynamic moving ripple sounds were presented while recording neural responses from each position. This dynamic stimulus contains spectral and temporal features commonly found in natural sounds ( Rodriguez et al., 2010 ) that effectively drive ICC neurons and which can be used to estimate STRFs ( Escabí and Schreiner, 2002 ).
