1. The Application of P300-Long-Latency Auditory-Evoked Potential in Parkinson Disease
Abstract Introduction Parkinson disease (PD) is a degenerative and progressive neurological disorder characterized by resting tremor, stiffness, bradykinesia, and postural instability. Despite the motor symptoms, PD patients also consistently show cognitive impairment or executive dysfunction. The auditory event-related potential P300 has been described as

2. Is there a change in P300 evoked potential after 6 months in cochlear implant users?
Abstract Objective: There are few studies on long-latency auditory evoked potential (P300) in people with hearing loss who use a cochlear implant. Central auditory system evaluation with behavioral and electrophysiological tests is believed to help understand the neuroplasticity mechanisms involved in auditory functioning after cochlear implant surgery. Thi

3. The Effect of Learning English on P300 in Children
Abstract Introduction Learning a second language is an essential task in today's world, and is experienced by many children. The cognitive auditory-evoked potential (P300) is related to cognitive activity, attention and concentration, enabling the investigation of the effect of a second language on the central auditory pathway. Objective To analyze the eff

4. Long-term Effects of Unilateral and Bilateral Otitis Media and Myringotomy on Long-Latency Verbal and Non-Verbal Auditory-Evoked Potentials
Abstract Introduction Otitis media (OM) is considered one of the most common reasons patients seek medical care in childhood. The fluctuating nature of hearing loss in cases of OM leads to irregular sound stimulation of the central auditory nervous system. Objectives To analyze the long-latency auditory-evoked potential (LLAEP) by verbal and nonverbal soun

5. Cognitive Auditory Evoked Potential in children with speech sound disorders: analysis of different verbal stimuli
ABSTRACT Objective: to analyze the influence of different combinations of verbal stimuli on the responses of the cognitive auditory evoked potential of children with speech sound disorders and to compare the P300 responses, considering the combinations of stimuli in the different severity of speech sound disorders. Methods: nineteen children in the mean ag

6. Influence of speech-language therapy on P300 outcome in patients with language disorders: a meta-analysis
Resumo Introdução: A evolução do paciente na clínica fonoaudiológica atua como fator motivador do processo terapêutico, contribui para a sua adesão ao tratamento e possibilita ao terapeuta a revisão e/ou a manutenção de suas condutas. As medidas eletrofisiológicas, como o potencial evocado P300, auxiliam na avaliação, na compreensão e no moni

7. Monitoring auditory cortical plasticity in hearing aid users with long latency auditory evoked potentials: a longitudinal study
OBJECTIVE: The objective of this study was to compare long-latency auditory evoked potentials before and after hearing aid fittings in children with sensorineural hearing loss compared with age-matched children with normal hearing. METHODS: Thirty-two subjects of both genders aged 7 to 12 years participated in this study and were divided into two groups as

8. Test-Retest of Long Latency Auditory Evoked Potentials (P300) with Pure Tone and Speech Stimuli
Abstract Introduction Long latency auditory evoked potentials, especially P300, have been used for clinical evaluation of mental processing. Many factors can interfere with Auditory Evoked Potential - P300 results, suggesting large intra and inter-subject variations. Objective The objective of the study was to identify the reliability of P3 components (l

9. Influence of antihypertensive drugs on aortic and coronary effects of Ang-(1-7) in pressure-overloaded rats
This study investigated the influence of antihypertensive drugs, such as angiotensin-converting enzyme inhibitors (ACEIs), AT1 receptor blockers (ARBs), voltage-gated L-type calcium channel blockers, and mineralocorticoid receptor antagonists (MRAs), on the effects of angiotensin-(1-7) [Ang-(1-7)] on aorta and coronary arteries from pressure-overloaded rats.

10. Auditory Evoked Potentials with Different Speech Stimuli: a Comparison and Standardization of Values
Abstract Introduction Long Latency Auditory Evoked Potentials (LLAEP) with speech sounds has been the subject of research, as these stimuli would be ideal to check individualś detection and discrimination. Objective The objective of this study is to compare and describe the values of latency and amplitude of cortical potentials for speech stimuli in adu

11. Recuperação postural em usuários de implante coclear com bom e mau desempenho auditivo / Postural recovery in cochlear implant users with good and poor hearing performance
OBJETIVO: verificar a inter-relação entre a recuperação postural e o bom ou baixo desempenho de indivíduos usuários de implante coclear (IC). MÉTODO: Foram avaliados 21 indivíduos divididos em três grupos: nove usuários de IC com bom desempenho, cinco de IC com baixo desempenho e sete controles. Todos os sujeitos foram submetidos a dois testes: Tes

12. Eletrofisiologia da audição em indivíduos com vestibulopatias periféricas pré e pós reabilitação vestibular / Electrophysiological evaluation of hearing in individuals with peripheral vestibular disorders before and after vestibular rehabilitation therapy
INTRODUCTION: The auditory evoked potentials assess the neuroelectrical activity of the auditory pathway from the auditory nerve to the cerebral cortex. The vectoelectronystagmography analyzes the semicircular canals and/or inferior vestibular nerve, checking peripheral or central vestibular involvement. The vestibular rehabilitation therapy consists in acti
