1. 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.

2. 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

3. 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

4. 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

5. 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

6. 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

7. 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

8. 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

9. Processamento temporal e resposta auditiva de média latência em idosos candidatos e usuários de prótese auditiva
Introduction: Aging can cause alterations in temporal processing and cognitive functions. Electrophysiological evaluation has been widely recommended to complement the behavioral evaluation of auditory processing. Objective: Verify and compare the behavioral auditory responses of temporal processing and the auditory middle latency response with cognitive pro

10. Behavioral, electroacoustic and electrophysiological assessment of hearing in autism. / "Avaliação comportamental, eletroacústica e eletrofisiológica da audição em autismo"
INTRODUCTION: Autism is a disorder, which begins in the infancy, and the main characteristics are the presence of an abnormal or impaired development of social interaction and communication, and restrict range of activities and interest. Some theories consider autism as a developmental disorder caused by a central nervous system alteration, and stress the pr

Objective: To verify the effects of a formal auditory training program in adult hearing aid users with mild to moderate sensorineural hearing loss using behavioral auditory processing tests, a self-report benefit scale and long latency auditory evoked potential P300. Method: Fourteen intra-aural hearing aid users were divided into two groups: seven with audi

12. Electrophysiological hearing evaluation in children with phonological disorder pre and post speech therapy / Avaliação eletrofisiológica da audição em crianças com distúrbio fonológico pré e pós terapia fonoaudiológica
INTRODUCTION: the phonological disorder is a speech disorder that may occur in one or more levels that are responsible for the development of the phonological system. Such levels are: speech production and perception, and rules organization. For a normal development of the phonological system, as well as of other aspects of language, it is necessary the inte
