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 …

WebOct 1, 2009 · Using complex stimuli, such as dynamic ripples and natural sounds, it is possible to derive the neuronal population preference to spectrotemporal acoustic properties beyond frequency (39). WebMar 3, 2010 · Methodology/principal findings: We studied the relationships between functional connectivity and receptive field properties in this columnar microcircuit by simultaneously recording from single neurons in cat AI in response to broadband dynamic moving ripple stimuli. We used spectrotemporal receptive fields (STRFs) to estimate … citi training boston university

WebJan 1, 2005 · The dynamic IRN stimulus further highlights the sensitivity of the system to temporal correlations. In previous experiments in which we investigated the perception of … WebNov 1, 2009 · We used temporally orthogonal ripple combinations (TORCs; for details, see, e.g., Klein et al. 2000) and dynamic moving ripples (DMRs; for details, see, e.g., Escabí and Schreiner 2002) to examine how changes in amplitudes and frequencies in conditioning stimuli contribute to the context-dependence effects (over the maximum range of 40 dB … Webother hand, is offered by the use of the dynamic moving ripple sound (DMR) which contains dynamically varying combinations of frequency and amplitude modulations. This artificial sound can be parametrically manipulated, allowing for the characterization of neuronal preferences over a broad spectrotemporal range (Escab´ı and Schreiner, 2002). dibutyl phthalate for sale
