Objectives: to verify the effects of a speech therapy intervention program in children after moderate and severe traumatic brain injury using electrophysiological behavioral assessment central auditory processing. Method: Five aged 9 11 years old who suffered closed trauma or degree for at least 6 months, right-handed, literate before injury, diagnosed with Central Auditory Processing Reading W...

Human auditory electromagnetic brain responses to sinusoidal (tone) and speech stimuli (Finnish vowel /a/ with two different glottal excitations) were studied with whole-head magnetoencephalogram (MEG) and electrodes placed on the subject's scalp. The frequency and intensity of the sinusoidal stimulus were optimally adjusted to match the spectra of the speech stimuli. Both tone and speech sound...

Event-related potentials were measured in twenty-four children aged 6-15 years, at one-year intervals for two years, to investigate developmental changes in each subject's neural response to a point-light walker (PLW) and a scrambled PLW (sPLW) stimulus. One positive peak (P1) and two negative peaks (N1 and N2) were observed in both occipitotemporal regions at approximately 130, 200, and 300-40...

We studied auditory evoked potentials (AEPs) in an 82-year-old female patient who became suddenly deaf following the second of two strokes. The patient showed markedly elevated pure tone thresholds, was unable to discriminate sounds and could not understand speech. Brain-stem auditory evoked potentials (BAEPs) were normal. CT scans revealed bilateral lesions of the superior temporal plane which...

background: the incomplete maturation of brain in preterm children results in long-term neurodevelopmental impairment. this study aimed to investigate the static balance function in children with a history of preterm birth. methods: participants were 31 preterm children including 21 moderately preterm (mpt), 10 very preterm (vpt), and 20 term children aged 5.5 and 6.5 years. the cervical vestib...

Vestibular-evoked myogenic potential (VEMP) testing is a vestibular function test used for evaluating saccular and inferior vestibular nerve function. Parameters of VEMP testing include VEMP threshold, latencies of p1 and n1, and p1-n1 interamplitude. Less commonly used parameters were p1-n1 interlatency, interaural difference of p1 and n1 latency, and interaural amplitude difference (IAD) rati...

Abstract Depression is intrinsically linked to sleep, however, the exact nature of sleep disturbances has been poorly defined, especially for older adults over 50 years with depression. We examined published articles overnight EEG recordings in and without depression determine if objective measures macro micro architecture differ. also differences these outcomes adults. 2135 papers were identif...

There have been disparate findings reported previously by investigators who have examined differences in the cortically generated N1 (i.e., N100) from control and tinnitus samples. Investigators have employed differing stimulation paradigms applied to relatively small subject samples. Accordingly, it is not surprising that there has been no unanimity in the reported findings. The present invest...

OBJECTIVE To compare P1-N1-P2-N2 response latencies and amplitudes evoked by voiced and unvoiced consonant-vowel syllables (CVS) /bi/-/pi/ and /di/-/ti/ by analyzing how the cortical responses to consonants and vowels interact during the formation of a syllable-evoked response. MATERIALS AND METHODS Auditory late latency responses were recorded from 12 healthy individuals between the ages of ...

Objectives: Inferior oblique muscle overaction (IOOA) is a common ocular motility disorder. Ocular Vestibular Evoked Myogenic Potentials (oVEMP) are tests that evaluate the reflex pathway between utricular macula and inferior to detect vestibular diseases. Our study of great importance as it first in literature effect on oVEMP parameters. Methods: Thirty-five patients with unilateral (IOOA grou...
