Background:Newborn hearing screening with automated procedures usually uses broad band stimuli, such as click. Studies using the Auditory Steady-State Response (ASSR) that used specific frequency chirps named narrow CE-chirps have shown obvious diagnostic results. Objective:To assess value of binaural multi-frequency chirp ASSR a tool. To compare and click ABR tool for early diagnosis loss in i...

OBJECTIVE To determine whether neurophysiological auditory brainstem responses to clicks and repeated speech stimuli differ between typically developing children and children with phonological disorders. INTRODUCTION Phonological disorders are language impairments resulting from inadequate use of adult phonological language rules and are among the most common speech and language disorders in ...

Nowadays, it is widely believed that the temporal structure of the auditory nerve fibers' response to sound stimuli plays an important role in auditory perception. An influential hypothesis is that information is extracted from this temporal structure by neural operations akin to an autocorrelation algorithm. The goal of the present work was to test this hypothesis. The stimuli consisted of seq...

In the synchrony judgment paradigm, observers judge whether a click precedes or follows the onset of a light flash and, on other trials, whether or not a click precedes light termination. The interclick interval defines the duration of visible persistence. An elaboration of this method consists of two phases: In Phase 1, the luminance of a reference stimulus is psychophysically matched to the p...

The presence of cross-sensory influences on neuronal responses in primary sensory cortex has been observed previously using several different methods. To test this idea in rat S1 barrel cortex, we hypothesized that auditory stimuli combined with whisker stimulation ("cross-sensory" stimuli) may modify response levels to whisker stimulation. Since the brain has been shown to have a remarkable ca...
