Dynamic moving ripples
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. WebOct 1, 2011 · a dynamic moving ripple stimulus in the primary auditory cortex of the cat.

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).

We 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. Since naturalistic stimuli are usually more sustained, have broader bandwidth, … See more For a subset of neurons, the same DMR stimulus was presented a second time (e.g., Supplementary Fig. 2a). Correlations between the resulting STRFs for both large and small … See more Because spectral and temporal modulations are inherent features of natural sounds, it is important to understand how modulation information carried by synaptic … See more The frequency extent of TRFs is strongly intensity dependent (Fig. 1a, b).
