Brainstem auditory evoked potentials with speech stimulus in neonates

Abstract Introduction: Brainstem auditory evoked potentials in response to complex sounds, such as speech sounds, investigate the neural representation of these sounds at subcortical levels, and faithfully reflect the stimulus characteristics. However, there are few studies that utilize this type of sti...

Padronização dos parâmetros latência e amplitude no registro dos potenciais evocados auditivos de tronco encefálico com o estímulo Ichirp de banda estreita em adultos audiologicamente normais

Audiol., Commun. res; 25 (), 2020
RESUMO Objetivo Padronizar os parâmetros de latência e amplitude obtidos com o estímulo Ichirp de banda estreita, na pesquisa dos potenciais evocados auditivos de tronco encefálico nas frequências de 500 Hz, 1 kHz, 2 kHz e 4 kHz. Métodos O estudo foi realizado na Divisão de Saúde Auditiva do Ho...

Long-latency auditory evoked potential in children with stuttering

ABSTRACT Objective To analyze the latency and the amplitude values of Mismatch Negativity and P300 cognitive potential in children with stuttering, with no auditory complaints, with auditory thresholds within the normality range, comparing them to the findings of a Control Group. Methods A cross-sect...

Use of technological tools to evaluate handwriting production of the alphabet and pseudocharacters by Brazilian students

Clinics; 74 (), 2019
OBJECTIVE: This study aimed to characterize and compare the handwriting performance of Brazilian students from the 3rd to the 5th grade level of elementary school I with a computerized instrument that allowed the real performance to be observed during the execution of the handwriting. METHODS: Ninety-fi...

Latent class analysis of attention and white matter correlation in children with attention-deficit/hyperactivity disorder

Braz. j. med. biol. res; 51 (11), 2018
This study aimed to explore attentional patterns among children with inattentive attention-deficit/hyperactivity disorder (ADHD-I) and children with typical development (TD), using a latent class analysis (LCA). Patterns of brain connectivity were also explored. The sample comprised 29 ADHD-I and 29 TD m...

Phrenic nerve conduction studies: normative data and technical aspects

Arq. neuropsiquiatr; 75 (12), 2017
ABSTRACT Objective: The aim of the present study was to define normative data of phrenic nerve conduction parameters of a healthy population. Methods: Phrenic nerve conduction studies were performed in 27 healthy volunteers. Results: The normative limits for expiratory phrenic nerve compound muscle ac...

Aging and wave-component latency delays in oVEMP and cVEMP: a systematic review with meta-analysis

Abstract Introduction: The natural aging process may result in morphological changes in the vestibular system and in the afferent neural pathway, including loss of hair cells, decreased numbers of vestibular nerve cells, and loss of neurons in the vestibular nucleus. Thus, with advancing age, there shou...

LS CE-Chirp® vs. Click in the neuroaudiological diagnosis by ABR

Abstract Introduction: The chirp stimulus was developed seeking to counterbalance the delay of the sound wave on its journey through the cochlea, allowing the hair cells to depolarize at the same time. The result is a simultaneous stimulation providing better neural synchrony and, consequently, the reco...

Temporal processing and long-latency auditory evoked potential in stutterers

Abstract Introduction: Stuttering is a speech fluency disorder, and may be associated with neuroaudiological factors linked to central auditory processing, including changes in auditory processing skills and temporal resolution. Objective: To characterize the temporal processing and long-latency audito...

Análise do tempo de reação e a correlação com quedas e seus danos em idosos

O tempo de reação é a capacidade de reagir com maior rapidez de movimento, de acordo com o condicionamento específico. Sabe-se que com envelhecimento ocorre diminuição das respostas aos estímulos externos podendo acarretar quedas, cuja prevenção se deve a manutenção do equilíbrio postural, o ...
