Does the neonate's brain have left hemisphere (LH) dominance for speech? Twelve full-term neonates participated in an optical topography study designed to assess whether the neonate brain responds specifically to linguistic stimuli. Participants were tested with normal infant-directed speech, with the same utterances played in reverse and without auditory(More)
Stimulus-locked temporal codes are increasingly seen as relevant to perception. The timing of action potentials typically varies with stimulus intensity, and the invariance of temporal representations with intensity is therefore an issue. We examine the timing of action potentials in cat auditory nerve to broadband noise presented at different intensities,(More)
OBJECTIVE One of the strategies to improve cochlear implant technology is to increase the number of electrodes in the neuro-electronic interface. The objective was to characterize in vitro cultures of spiral ganglion neurons (SGN) cultured on surfaces of novel silicon micro-pillar substrates (MPS). APPROACH SGN from P5 rat pups were cultured on MPS with(More)
Frequency selectivity is a fundamental cochlear property. Recent studies using otoacoustic emissions and psychophysical forward masking suggest that frequency selectivity is sharper in human than in common laboratory species. This has been disputed based on reports using compound action potentials (CAPs), which reflect activity in the auditory nerve and can(More)
Gender identification of human voices was studied in a juvenile population of cochlear implant (CI) users exposed to naturalistic speech stimuli from 20 male and 20 female speakers using two different voice gender perception tasks. Stimulus output patterns were recorded from each individual CI for each stimulus, and features related to voice fundamental(More)
In five experiments highly-proficient bilinguals were asked to name two sets of pictures in their L2: a) pictures whose names in the L2 and their corresponding L1 translations have the same grammatical gender value, and b) pictures whose names in the L2 and their corresponding L1 translations have different gender values. In Experiments 1, 2, and 3(More)
The authors report 3 picture-word interference experiments in which they explore some properties of the agreement process in speech production. In Experiment 1, Croatian speakers were asked to produce utterances in which the noun's gender value had an impact on the selection of gender-marked freestanding morphemes (pronouns) while ignoring the presentation(More)
OBJECTIVES The study was carried out to assess the role that five hearing history variables (chronological age, age at onset of deafness, age of first cochlear implant [CI] activation, duration of CI use, and duration of known deafness) play in the ability of CI users to identify speaker gender. DESIGN Forty-one juvenile CI users participated in two voice(More)
Peptide hormones depend on reliable recognition by their receptors. Any mutation that compromises recognition of hormone and receptor molecules is dangerous, the carrier animal would not procreate and the mutation would be lost. Although, most of the hormones from one mammalian species are active when injected into another, the incompatibility of human GH(More)
The aim of this paper is to present the topographical/anatomical conditions that protect the posterior fossa from posterior fossa hematoma (PFH) resulting from contrecoup mechanisms and to point out the value of neuroradiological findings in determining force direction and transition. The biomechanism of this clinical entity also plays an important role in(More)
