Dynamic moving ripples
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 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 …
