Mismatch negativity in childhood temporal lobe epilepsy: a proposed paradigm fo...

Tomé, David; Moreira, Pedro; Marques-Teixeira, João; Barbosa, Fernando; Jääskeläinen, Satu

Background: Temporal lobe epilepsy (TLE) is a neurological disorder that directly affects cortical areas responsible for auditory processing. The resulting abnormalities can be assessed using event-related potentials (ERP), which have high temporal resolution. However, little is known about TLE in terms of dysfunction of early sensory memory encoding or possible correlations between EEGs, linguistic deficits, a...


Differences in Mismatch Negativity (MMN) response to Pure-tone and Speech sound...

Tomé, David; Barbosa, Fernando; Marques-Teixeira, João

The relation of automatic auditory discrimination, measured with MMN, with the type of stimuli has not been well established in the literature, despite its importance as an electrophysiological measure of central sound representation. In this study, MMN response was elicited by pure-tone and speech binaurally passive auditory oddball paradigm in a group of 8 normal young adult subjects at the same intensity lev...


Hearing evaluation of portuguese school communities: school‑based audiology and...

Tomé, David; Lopes, Paula; Sousa, Aida; Magalhães, António

Introduction: Hearing loss h sone raised impact in the development and academic progress of a child. In several developed countries, early detection is part of the national health plan through universal neonatal hearing screening (UNHS) and also with school hearing screening programs (SHSP), but only a few have published national data and revised protocols. Currently in Portugal, the UNHS is implemented in the ...


Analysis of the combined exposure to noise and ototoxic substances—pilot study

Lopes, Marta; Tomé, David; Carmo, Paulo Cardoso do; Rodrigues, M. A.; Neves, Paula

Abstract: Ototoxic substances have been associated to damage of the auditory system, and its effects are potentiated by noise exposure. The present study aims at analyzing auditory changes from combined exposure to noise and organic solvents, through a pilot study in the furniture industry sector. Audiological tests were performed on 44 workers, their levels of exposure to toluene, xylene and ethylbenzene were ...

Temporal lobe epilepsy in childhood – a study model of auditory processing

Tomé, David; Marques-Teixeira, João; Barbosa, Fernando

TLE in infancy has been the subject of varied research. Topographical and structural evidence is coincident with the neuronal systems responsible for auditory processing of the highest specialization and complexity. Recent studies have been showing the need of a hemispheric asymmetry for an optimization in central auditory processing (CAP) and acquisition and learning of a language system. A new functional rese...


Intervenção do Fisioterapeuta na (dis)função respiratória em Pediatria - da com...

Tomé, David

O ouvido médio (OM) é responsável pela transdução do som canalizado pelo ouvido externo, enquanto energia acústica em meio aéreo, para energia hidromecânica no ouvido interno onde ocorrem fenómenos de despolarização celular bioeléctrica que originam potenciais eléctricos conduzidos pelo nervo vestíbulo-coclear e posteriores vias neuronais até ao córtice. O seu correcto funcionamento é por isso imprescindível pa...
