Hiperacusia: considerações teóricas
(Universidade Federal de Santa MariaCentro de Ciências da Saúde, 2004-12)
The daily sound discomfort is called hyperacusis. This alteration is defined as an
abnormal reaction of the auditory pathway in relation to the outside sounds,
generally the ones that have moderate or weak intensity, but ...
O papel do sistema olivococlear medial em crianças portadoras de TDAH
(Associação Brasileira de Otorrinolaringologia e Cirurgia Cervicofacial, 2012-06)
Crianças portadoras de Transtorno do Déficit de Atenção/Hiperatividade (TDAH) apresentam como um de seus principais sintomas a dificuldade de atenção. Na audição, a Atenção Seletiva que se caracteriza por ser a capacidade ...
Age impact on the eferent system actitivies in cochlear mechanical properties in normal hearing individuals
(Associação Brasileira de Otorrinolaringologia e Cirurgia Cervicofacial, 2009-06-01)
O trato olivococlear medial realiza o controle eferente das células ciliadas externas, regulando as contrações lentas e atenuando as rápidas. Com a pesquisa da amplitude das emissões otoacústicas sem e com estimulação ...

Influência da idade na atividade do sistema eferente nas propriedades mecânicas da cóclea de ouvintes normais
(2009-01-01)
The medial olivocochlear tract has efferent control over the outer hair cells, regulating the slow contractions and damping the fast ones. Using ipsilateral, contralateral or bilateral otoacoustic emissions amplitude ...
O cigarro como um fator de risco para alterações auditivas
(Associação Brasileira de Otorrinolaringologia e Cirurgia Cervicofacial, 2009-12-01)
Smoking is a public health concern and we are still unsure of its relation with auditory problems. AIM: To study the effects of cigarette smoking in auditory thresholds, in otoacoustic emissions and in their inhibition by ...
The Cholinergic Lateral Line Efferent Synapse: Structural, Functional and Molecular Similarities With Those of the Cochlea
(Frontiers Media, 2021-10)
Vertebrate hair cell (HC) systems are innervated by efferent fibers that modulate their response to external stimuli. In mammals, the best studied efferent-HC synapse, the cholinergic medial olivocochlear (MOC) efferent ...
Contralateral-noise effects on cochlear responses in anesthetized mice are dominated by feedback from an unknown pathway
(American Physiological Society, 2012-07)
Suppression of ipsilateral distortion product otoacoustic emissions (DPOAEs) by contralateral noise is used in humans and animals to assay the strength of soundevoked negative feedback from the medial olivocochlear (MOC) ...
The nicotinic receptor of cochlear hair cells: A possible pharmacotherapeutic target?
(Pergamon-Elsevier Science Ltd, 2009-10)
Mechanosensory hair cells of the organ of Corti transmit information regarding sound to the central nervous system by way of peripheral afferent neurons. In return, the central nervous system provides feedback and modulates ...
