1. The Application of P300-Long-Latency Auditory-Evoked Potential in Parkinson Disease
Abstract Introduction Parkinson disease (PD) is a degenerative and progressive neurological disorder characterized by resting tremor, stiffness, bradykinesia, and postural instability. Despite the motor symptoms, PD patients also consistently show cognitive impairment or executive dysfunction. The auditory event-related potential P300 has been described as

2. Mismatch Negativity Occurrence with Verbal and Nonverbal Stimuli in Normal-Hearing Adults
Abstract Introduction The mismatch negativity (MMN) is a long-latency auditory evoked potential related to a passive elicited auditory event. Objective To verify the occurrence of MMN with different stimuli, to describe reference values in normal-hearing adults with verbal and nonverbal stimuli and to compare them with each other, besides analyzing the l

3. Neuro-behavioral pattern of sleep bruxism in wakefulness
AbstractIntroduction: Sleep Bruxism (SB) is a non-functional rhythmic movement of the mandible with multifactorial aetiology and complex diagnose. It has been the subject of various studies over the past decades and it is considered a result of actions of the Central Nervous System modulated by Autonomous Nervous System. In this work, we test the hypothesis

4. Aplicabilidade do Mismatch Negativity na população infantil: revisão sistemática de literatura
RESUMO Introdução Mismatch Negativity (MMN) é um potencial eletrofisiológico que mede a habilidade do cérebro em discriminar sons, independente da capacidade atencional e comportamental. Por ser uma medida objetiva e de fácil utilização, torna-se promissora no estudo da investigação do processamento auditivo em crianças. Objetivo Verificar a ap

5. Mismatch Negativity: analysis of temperature and auditory training effects from an experimental study model. / Mismatch negativity: análise dos efeitos da hipotermia e do treinamento auditivo a partir de um modelo de estudo experimental
INTRODUCTION: Significant ischemic cerebral lesions may result in cognitive disorders of varying degrees, with clinical repercussions that could be extremely severe for the affected patients. In order to evaluate the consequences of such lesions upon functional aspects, one of the components of event-related auditory evoked potentials, the Mismatch Negativit

6. AGE RELATED EFFECTS ON P300 AUDITORY EVOKED POTENTIAL LATENCY / O EFEITO DA IDADE SOBRE A LATÊNCIA DO POTENCIAL EVOCADO AUDITIVO P300
Esta pesquisa teve por objetivo estimar o efeito da idade sobre a latência do Potencial Evocado Auditivo P300 em um grupo de idosos. Foram estudados 62 idosos saudáveis, com limiares tonais iguais ou menores do que 40 dBNA nas freqüências de 1000 e 2000 Hz, de ambos os gêneros, 19 com idades entre 60 e 64 anos( Grupo 60), 22 com idades entre 65 e 69 ano

7. Electrophysiological hearing evaluation in children with phonological disorder pre and post speech therapy / Avaliação eletrofisiológica da audição em crianças com distúrbio fonológico pré e pós terapia fonoaudiológica
INTRODUCTION: the phonological disorder is a speech disorder that may occur in one or more levels that are responsible for the development of the phonological system. Such levels are: speech production and perception, and rules organization. For a normal development of the phonological system, as well as of other aspects of language, it is necessary the inte

8. Behavioral, electroacoustic and electrophysiological assessment of hearing in autism. / "Avaliação comportamental, eletroacústica e eletrofisiológica da audição em autismo"
INTRODUCTION: Autism is a disorder, which begins in the infancy, and the main characteristics are the presence of an abnormal or impaired development of social interaction and communication, and restrict range of activities and interest. Some theories consider autism as a developmental disorder caused by a central nervous system alteration, and stress the pr

9. Investigation of inter and intra-examiner stability to P300 auditory identification: analysis of errors. / Investigação da estabilidade inter e intra-examinador na identificação do P300 auditivo: análise de erros.
The P300 auditory is an evoked potential which reflects the neurophysiological activity of auditory cognitive abilities: attention, memory, discrimination and making decision as well. The possibility of correlation between aspects of auditory behavior and observable physiological phenomena has increased the interest in the study of auditory dysfunctions amon

10. Neural fate of seen and unseen faces in visuospatial neglect: A combined event-related functional MRI and event-related potential study
To compare neural activity produced by visual events that escape or reach conscious awareness, we used event-related MRI and evoked potentials in a patient who had neglect and extinction after focal right parietal damage, but intact visual fields. This neurological disorder entails a loss of awareness for stimuli in the field contralateral to a brain le

12. Sensory and cognitive event-related potentials in myalgic encephalomyelitis.
Myalgic Encephalomyelitis (ME) is a form of post viral fatigue syndrome resulting in myalgia and fluctuating fatiguability. Symptoms reflecting central nervous system dysfunction are common and include muscle weakness, headache, sensory disturbances, poor short term memory and impairment of concentration. In view of the fact that sensory and cognitive distur
