1. The effect of increase in blood glucose level on hearing loss
Abstract Objective: Previous studies have shown that hearing function is also vulnerable to the effects of diabetes mellitus which can be shown by brainstem auditory evoked potential and distortion product otoacoustic emission recordings. This study aimed to investigate the changes of brainstem auditory evoked potential and distortion product otoacoustic em

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 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

4. Reliability of Contralateral Suppression in Evoked Distortion Product Otoacoustic Emissions
Abstract Introduction Distortion product otoacoustic emissions (DPOAE) and their suppression may be considered useful in monitoring cochlear function and the efferent auditory pathway inhibitory effect. Nonetheless, the establishment of reliable parameters of response variations is of great importance. Objectives To verify the replicability of test and ret

5. 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

6. 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

7. Mismatch Negativity Elicited by Verbal and Nonverbal Stimuli: Comparison with Potential N1
Abstract Introduction Mismatch negativity (MMN) is a long latency auditory evoked potential, represented by a negative wave, generated after the potential N1 and visualized in a resulting wave. Objective To identify the time of occurrence ofMMNafter N1, elicited with verbal and nonverbal stimuli. Methods Ninety individuals aged between 18 and 56 years

8. Mismatch Negativity Occurrence with Verbal and Nonverbal Stimuli in Normal-Hearing Adults
Abstract Introduction The mismatch negativity (MMN) is a long-latency auditory evoked potential related to a passive elicited auditory event. Objective To verify the occurrence of MMN with different stimuli, to describe reference values in normal-hearing adults with verbal and nonverbal stimuli and to compare them with each other, besides analyzing the l

9. Pure-Tone Hearing Thresholds and Brainstem Auditory Evoked Potentials in Sporadic Ataxia
Abstract Introduction Spinocerebellar ataxia (SCA) is part of a genetic and clinical heteroge- neous group of neurodegenerative diseases characterized by progressive cerebellar ataxia. Objective To describe the results of audiological and electrophysiological hearing evaluations in patients with sporadic ataxia (SA). Methods A retrospective cross-secti

10. 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

11. Frequency-Following Response with Speech Stimulus: Comparison between Two Methods of Stimulation
Abstract Introduction Frequency-following response with speech stimulus (FFR-speech) is a subcortical potential that satisfactorily evaluates the processing of verbal information. However, there still are differences in the literature regarding its analysis and stimulation protocol. Objective To compare two stimulation protocols for the capture of FFR-sp

12. Mismatch Negativity in Childrenwith Cochlear Implant
Abstract Introduction The mismatch negativity (MMN) is a negative long-latency auditory potential elicited by any discriminable change in a repetitive aspect of auditory stimulation. This evoked potential can provide cortical information about the sound processing, including in children who use cochlear implants. Objective To identify MMN characteristics
