“…It also corroborates the assertion of Pammer [18], who reported that structural changes in the brain are observed as consequences of phonological and reading intervention. In this way, this study confirms that P300 is a viable tool to measure and monitor neurophysiological modifications of the central auditory nervous system, corroborating the claims of Alonso and Schochat [26] and Anderson et al [27].…”

“…The AEP is a cognitive potential generated by a complex neural network between the thalamus, temporal-parietal cortex, prefrontal cortex, and hippocampus region. In studying AEP, two components can be evaluated, the N2 (or N200), which is associated with the perception, discrimination, recognition, and classification of an auditory stimulus, and P3 (or P300), which occurs when the individual consciously recognizes the presence of a change in the auditory stimulus [26,27]. Also, it has been shown to be an effective tool in the objective evaluation of auditory attention in children with phonological deficits, short-term memory, and reading and writing alterations [28].…”

Objective: To determine the effects of a phonological remediation reading and writing program in individuals with dyslexia, through behavioral and objective evaluations. Patients and Methods: Twenty children diagnosed with dyslexia, aged 8–14 years, were included in this study. Group I (GI) was composed of 10 children who took part in the program, and group II (GII) consisted of 10 subjects who did not take the remediation. The pre-testing evaluated phonological awareness, rapid naming, working memory, reading and writing of words and nonwords, thematic writing, and auditory evoked potential – P300. The type of stimulus used was the speech (20% of rare stimulus and 80% of frequent stimulus), intensity of 80 dBNa. The rare stimulus was the syllable /da/, and the frequent stimulus was the syllable /ba/. Next, the Phonological Reading and Writing Remediation Program was applied in 24 cumulative sessions, twice a week, each with a duration of 30 min. In the post-testing (at the end of the program), all the tests of the pre-testing were reapplied. Results: There was a statistically significant difference (between pre- and post-testing) in phonological awareness, rapid naming, working memory, thematic writing, writing and reading words and nonwords, as well as in the latency of the P3 component of P300 in GI, while GII maintained the same difficulties. Conclusion: The phonological remediation program showed to be a therapeutic method of fast beneficial effects in written language of individuals with dyslexia. However, the wide age range and the size of the sample could be considered a limitation of this study – it interferes with the generalization of results.

“…In the literature, CAEP-P300 use to assess neurophysiological changes that happened after the hearing training was seen in patients with hearing process disorder (10) , in cases of disfluency (12) , as well as a predictor of the results of chemical dependence treatment (11) . In this study, CAEP-P300 was analyzed in two moments, before and after the phonological remediation, associated with reading and writing.…”

Purpose: To evaluate the cochlear function of parents of individuals with autosomal recessive gene Gap Junction Protein Beta-2 hearing loss by ultra-high frequencies distortion-product otoacoustic emissions (DPOAEs), compared with responses of a control group matched for age and gender. Methods: We studied 56 subjects aged from 20 to 58 years, divided into two groups. The study group comprised 28 parents of hearing-impaired patients due to autosomal recessive inheritance, 14 females aged 20.0-55.0 years (mean 32.8 years) and 14 males aged 20.0-58.0 years (mean 35.2 years). Control group was composed of normal hearing individuals, 14 males and 14 females age-matched to the study group. The subjects underwent tests for audiometry, tympanometry, and DPOAE in the frequency range of 9.000-16.000 Hz. Results: We found 64.3% of normal results of DPOAE in the study group compared to 91.1% in the control. There were significant differences between groups in the ears and DPOAE responses, and the mean level of response was in 10 dBNPS in study group and 14 dBNPS in the control. The Pearson's correlation between age and DPOAE in ultra-high frequencies showed no statistical significance. Conclusion: DPOAE at ultra-high frequencies were able to identify individuals from both groups, suggesting that heterozygous individuals for the Gap Junction Protein Beta-2 gene mutation may have damage to the cochlear function before clinical manifestation in audiometry.

“…In studies of substance abuse treatment completion with community samples, reduced P300 amplitude has been associated with treatment discontinuation and relapse (Bauer 1997, 2001a; Anderson et al. 2011). Reduced P300 amplitudes associated with treatment discontinuation and relapse are typically elicited during processing of task‐irrelevant distractor stimuli.…”

Brain potentials predict substance abuse treatment completion in a prison sample

IntroductionNational estimates suggest that up to 80% of prison inmates meet diagnostic criteria for a substance use disorder. Because more substance abuse treatment while incarcerated is associated with better post‐release outcomes, including a reduced risk of accidental overdose death, the stakes are high in developing novel predictors of substance abuse treatment completion in inmate populations.MethodsUsing electroencephalography (EEG), this study investigated stimulus‐locked ERP components elicited by distractor stimuli in three tasks (VO‐Distinct, VO‐Repeated, Go/NoGo) as a predictor of treatment discontinuation in a sample of male and female prison inmates. We predicted that those who discontinued treatment early would exhibit a less positive P3a amplitude elicited by distractor stimuli.ResultsOur predictions regarding ERP components were partially supported. Those who discontinued treatment early exhibited a less positive P3a amplitude and a less positive PC4 in the VO‐D task. In the VO‐R task, however, those who discontinued treatment early exhibited a more negative N200 amplitude rather than the hypothesized less positive P3a amplitude. The discontinuation group also displayed less positive PC4 amplitude. Surprisingly, there were no time‐domain or principle component differences among the groups in the Go/NoGo task. Support Vector Machine (SVM) models of the three tasks accurately classified individuals who discontinued treatment with the best model accurately classifying 75% of inmates. PCA techniques were more sensitive in differentiating groups than the classic time‐domain windowed approach.ConclusionsOur pattern of findings are consistent with the context‐updating theory of P300 and may help identify subtypes of ultrahigh‐risk substance abusers who need specialized treatment programs.
