“…In our study, the speech stimuli were considered easier to identify than the tonal stimuli. Although verbal stimuli are more complex (18) , they are more familiar to the subjects as they are present in the mother tongue, while the tonal stimuli can have no meaning except for individuals with musical abilities (19) . Considering the results of the statistical analysis of this research, the P3 stimuli classified as the easiest (/Di/ and /Da/ stimulus presented lower latency, being statistically significant.…”

Purpose: Evaluating the level of difficulty of identifying verbal and non-verbal stimuli, according to the classification of the participants, as well as comparing the latency of the P3 cortical potential. Methods:Thirty subjects, with a mean age of 23 years and normal hearing, were evaluated. The P3 potential was performed with non-verbal stimuli (tone burst) and verbal (/ba/ x /di/, /ba/ x /ga/, /ba/ x /da/). Each subject had to classify stimulus in "the easiest" and "the most difficult". Results:Most subjects rated the /ba/ x /di/ contrast as the easiest to identify and the contrast /ba/ x /ga/ the most difficult. The subjects reported that the speech stimulus were easier to identify when compared to tone burst.

“…Em especial no que se refere ao contexto brasileiro, a parcimônia de estudos na área das neurociências envolvendo a música e suas capacidades cognitivas em adultos, como raciocínio, por exemplo, torna-se ainda maior. A grande contribuição que se tem a partir dos estudos da neurociência cognitiva refere-se à compreensão dos substratos neurais para se entender as bases biológicas do processamento musical (Nunes-Silva & Haase, 2013; Rabelo, Neves-Lobo, Rocha-Muniz, Ubiali, & Schochat, 2015) e/ou da organização cerebral para tal função (Muszkat, Correia, & Campos, 2000).…”

Este artigo tem por objetivo compreender a relação entre raciocínio e musicalidade em adultos. Sendo assim, para maior compreensão das habilidades cognitivas influenciadas pela atividade eufônica, uma pesquisa quantitativa foi realizada com 40 musicistas/instrumentistas, entre 18 e 64 anos (Média: 32,35 e DP:11,66), divididos em quatro grupos de acordo com a teoria organológica da execução dos instrumentos: três grupos (corda, sopro ou percussão) e um grupo de multi-instrumentistas. Em cada grupo foi aplicada a Bateria de Provas de Raciocínio (BPR-5), compreendendo as seguintes escalas: Raciocínio Verbal (RV), Raciocínio Numérico (RN), Raciocínio Abstrato (RA) e Raciocínio Espacial (RE). A aplicação das escalas permitiu entender se há relação entre a atividade exercida e/ou instrumento utilizado e o desempenho entre os diferentes tipos de raciocínio. Em relação às escalas, o grupo dos multi-instrumentistas apresentou desempenho melhor, em relação aos demais musicistas, em duas dessas (RA e RN); os demais resultados dos diferentes grupos expressaram médias favoráveis com base na padronização do BPR-5. Esses resultados preliminares, então, indicam que tipos diferenciados de raciocínio podem se desenvolver e relacionar com tipos específicos de musicistas.

“…The late auditory evoked potentials provide a non-invasive technique that reflects the neuroelectrical activity in the cortex as a response to a given stimulus [ 36 ]. There are very few studies in literature that recorded the late auditory potentials (LAP) and used masking broadband noise stimulation [ 25 , 37 , 38 , 39 , 40 , 41 ], which could provide some insight about the effects of olivocochlear activity on human auditory processing. Salo et al [ 39 ] recorded the LAP in normal hearing subjects and observed N1 amplitude reduction and P2 amplitude increase in the assessment with noise.…”

“…In contrast to this data, Polich et al [ 37 ] and Salisbury et al [ 38 ] verified latency increase for P300 wave in the presence of noise in adults with normal hearing. The studies of Schochat et al [ 25 ] and Rabelo et al [ 40 ], however, found no significant changes for P300 values in the assessment with contralateral noise for normal hearing subjects while Rabelo et al [ 40 ] observed that P300 latency increased in the presence of contralateral noise in a group of professional musicians. Nevertheless, the small number of studies and the contradictory results make it still not possible to determine the effects of the olivocochlear activity on cortical areas of the CANS.…”

Background and ObjectiveThe auditory cortex modulates auditory afferents through the olivocochlear system, which innervates the outer hair cells and the afferent neurons under the inner hair cells in the cochlea. Most of the studies that investigated the efferent activity in humans focused on evaluating the suppression of the otoacoustic emissions by stimulating the contralateral ear with noise, which assesses the activation of the medial olivocochlear bundle. The neurophysiology and the mechanisms involving efferent activity on higher regions of the auditory pathway, however, are still unknown. Also, the lack of studies investigating the effects of noise on human auditory cortex, especially in peadiatric population, points to the need for recording the late auditory potentials in noise conditions. Assessing the auditory efferents in schoolaged children is highly important due to some of its attributed functions such as selective attention and signal detection in noise, which are important abilities related to the development of language and academic skills. For this reason, the aim of the present study was to evaluate the effects of noise on P300 responses of children with normal hearing.MethodsP300 was recorded in 27 children aged from 8 to 14 years with normal hearing in two conditions: with and whitout contralateral white noise stimulation.ResultsP300 latencies were significantly longer at the presence of contralateral noise. No significant changes were observed for the amplitude values.ConclusionContralateral white noise stimulation delayed P300 latency in a group of school-aged children with normal hearing. These results suggest a possible influence of the medial olivocochlear activation on P300 responses under noise condition.

Cortical inhibition effect in musicians and non-musicians using P300 with and without contralateral stimulation

Abstract: The central auditory nervous system of musicians presents peculiar characteristics of electrophysiological responses probably due to the plasticity imposed by musical practice.
