“…The results indicated that the precision and magnitude of neural phase locking to F0, F1, and HF ranges were lower in CI-recipients. The F0 plays an essential role for perceiving the pitch of a person's voice, and contains a low-frequency component of speech sound; consequently, recognition of speaker sound, and the voice emotional tone is dependent on the F0 encoding [23]. Furthermore, F1 and HF are a series of the discrete peak in the formant structure that are responsible for the vowel perception, and provide some information regarding the stimuli phonetics; therefore, it could play a significant role in different capabilities of CI-recipients, and normal individuals in the different spectral processing at the brainstem level to speech signals [24].…”

Background and Objectives: Currently limited information is available on speech stimuli processing at the subcortical level in the recipients of cochlear implant (CI). Speech processing in the brainstem level is measured using speech-auditory brainstem response (S-ABR). The purpose of the present study was to measure the S-ABR components in the sound-field presentation in CI recipients, and compare with normal hearing (NH) children.Subjects and Methods: In this descriptive-analytical study, participants were divided in two groups: patients with CIs; and NH group. The CI group consisted of 20 prelingual hearing impairment children (mean age=8.90 ± 0.79 years), with ipsilateral CIs (right side). The control group consisted of 20 healthy NH children, with comparable age and sex distribution. The S-ABR was evoked by the 40-ms synthesized /da/ syllable stimulus that was indicated in the sound-field presentation.Results: Sound-field S-ABR measured in the CI recipients indicated statistically significant delayed latencies, than in the NH group. In addition, these results demonstrated that the frequency following response peak amplitude was significantly higher in CI recipients, than in the NH counterparts (<i>p</i><0.05). Finally, the neural phase locking were significantly lower in CI recipients (<i>p</i><0.05). Conclusions: The findings of sound-field S-ABR demonstrated that CI recipients have neural encoding deficits in temporal and spectral domains at the brainstem level; therefore, the sound-field S-ABR can be considered an efficient clinical procedure to assess the speech process in CI recipients.

“…In similar studies (3,9) , authors reported higher P3 latency averages in males. The results of this study can be explained by differences in auditory pathway functionality between genders (18) due to morphological and physiological aspects of the auditory pathway, as well as behavioral aspects (26,27) , who were pronounced in the group with Complaints of learning impairment, evidencing worse results in the processing of acoustic information at the central level for the male gender.…”

Introduction:Children with learning impairment complaints may show changes in the functioning of the central auditory system. The Long Latency Auditory Evoked Potential -P3 is useful in the functional evaluation of the central auditory structures, and can be used as an auxiliary method in the early identification of learning impairment. Purpose: To analyze and compare latencies and amplitudes obtained in P3 of children that complained or not of learning impairment with normal hearing. Methods: The sample consisted of 30 children complaining of learning impairment (study group) and 14 children that did not complain (control group), aged 9 years and 12 years and 11 months. All the children underwent peripheral audiologic evaluation and the P3 study. Results: It was found that the mean P3 latency of the study group was significantly higher than the control group. When comparing P3 amplitude values, there was no difference, although the mean of the study group was lower when compared to the control group. It was observed that, for age and P3 latency, no significant correlation was detected. A similar situation was observed in the relation of age and amplitude, which, even though negative, it was not significant. Conclusion:The group of children with learning impairment complaints presented P3 latency values greater than the children in the group of children that did not complain. No correlation was found in the P3 wave amplitude values between groups.

Background: The combination of acoustic and electric stimulation as a way to enhance speech recognition performance in cochlear implant (CI) users has generated considerable interest in the recent years. The purpose of this study was to evaluate the bimodal advantage of the FS4 speech processing strategy in combination with hearing aids (HA) as a means to improve low-frequency resolution in CI patients. Methods: Nineteen postlingual CI adults were selected to participate in this study. All patients wore implants on one side and HA on the contralateral side with residual hearing. Monosyllabic word recognition, speech in noise, and emotion and talker identification were assessed using CI with fine structure processing/FS4 and high-definition continuous interleaved sampling strategies, HA alone, and a combination of CI and HA. Results: The bimodal stimulation showed improvement in speech performance and emotion identification for the question/statement/order tasks, which was statistically significant compared to patients with CI alone, but there were no significant statistical differences in intragender talker discrimination and emotion identification for the happy/angry/neutral tasks. The poorest performance was obtained with HA only, and it was statistically significant compared to the other modalities. Conclusion: The bimodal stimulation showed enhanced speech performance in CI patients, and it improves the limitations provided by electric or acoustic stimulation alone.
