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 spectrotemporal envelope patterns in moving ripple noises, we found that subjects could discriminate upward from downward moving ripples only if the density of the spectral … WebMay 15, 2002 · Dynamic moving ripple envelope. The DMR envelope is designed as a dynamic sinusoidal grating on a octave frequency and decibel amplitude axis. Two …
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 … WebApr 13, 2024 · Dynamic pricing could easily end in frustrated customers or losing loyal customers who feel cheated or taken advantage of.

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 … WebNov 1, 1996 · 1.

WebMar 3, 2010 · Neurons were probed with pure tones, then with one or two presentations of a 15 or 20 minute dynamic moving ripple stimulus. The level and frequency of each pure tone was chosen randomly from 15 different levels (5 dB spacing) and 45 different frequencies. Each pure tone was presented 5 times at a given level and frequency.
WebJun 24, 2024 · Second, LFPs have response amplitudes that increase in a graded fashion with sound level ; however, peak amplitudes of the PPs were not correlated with the instantaneous sound pressure levels of the dynamic moving ripple (DMR) sounds (PP amplitudes versus instantaneous SPL of the DMR sound: r = 0.067 ± 0.053, mean ± SE). … opyt realty naples flWe studied the responses of A1 neurons to pure tones and dynamic broadband stimuli estimating both TRFs and STRFs. Recordings were obtained largely at depths corresponding to layer 4, the main hub receiving lemniscal thalamic inputs from the ventral medial geniculate body16. Tone-evoked membrane … See more Tone-evoked responses are characterized by highly synchronous synaptic inputs at the onset of the tones.
