Dynamic moving ripples
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 … WebTop: Moving ripples (MRs) at various temporal and spectral modulation frequencies. The modulation frequencies determine the presence, and orientation, of the frequency modulation in each MR.

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 … Webdynamic moving ripple; FMRP, fragile X mental retardation protein; Hz, kHz, hertz, kilohertz; MNTB, medial nucleus of the trapezoid body; OD, optical density; SPL, sound …
WebThe RP Dynamics team educates itself on a wide range of considerations including the time of year, venue, theme, number of guests, sponsors and stakeholders, and most … 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). We tested for the effects of variations in DMR intensity on STRFs by comparing three sound intensities (38, … See more
