“…For example, if the task consists of serial (e.g., arithmetical) or verbal information processing, ERPs to the probe are smaller over the left hemisphere; if on the other hand the task consists of visual-spatial operations or the evalutation of the emotional content of verbal information probe, ERPs are smaller over the right hemisphere. This probe-stimulus paradigm has been used in several studies with normal subjects and patients (De Pascalis, Marucci, & Penna, 1987;Papanicolaou, 1980;Papanicolaou, Levin, Eisenberg, & Moore, 1983;Selinger, Prescott, & Shucard, 1989;Shucard, Shucard, & Thomas, 1977). Papanicolaou, Levin, and Eisenberg (1984) compared three groups of right-handed subjects: 6 patients who had recovered from aphasia due to a focal left hemisphere lesion; 6 patients with diffuse lesions but without aphasic symptoms, and 8 normal subjects.…”

Investigations using event-related potentials (ERPs) in brain-injured patients affected by neuropsychological disorders of perception, attention, memory, and language, and other special syndromes such as blind-sight, neglect, prosopagnosia, and apraxia are reviewed. These electrophysiological techniques can be used to assess the integrity of specific brain processes during the performance of cognitive tasks in which behavioral impairments are observed. A special feature of ERP technique is that it reveals ongoing and covert processing which may not be fully assessed by measuring only overt behavioral performance.

“…The auditory P3 has been investigated most often in disorders of the brain and cognitive function, even though its neural generators are not yet fully understood (McCarthy et al, 1989;Knight et al, 1989;Wood, 1984). The P3 has been described in dementia, alcoholism, drug effects, hyperkinesias, Alzheimer's disease, Down's Syndrome, various psychiatric disorders, aging, and aphasia (Goodin et al, 1978;Herning and Jones, 1978;Loiselle et al, 1979;Pfefferbaum et al, 1979;Chayasirisobhom et al, 1985;Diner et al, 1985;Lincoln et al, 1985;Romani et al, 1987;Patterson et al, 1988;Polich and Starr, 1984;Selinger and Prescott, 1989).…”

Psychophysical and P300 (P3) thresholds and suprathreshold measures were obtained in 16 normal-hearing subjects. Subjects followed a classic oddball paradigm using 1000 (frequent) and 2000 Hz (rare) tones as stimuli. The P3 was obtained for all 16 subjects at or 5 dB above their behavioral threshold. The P3 was obtained more often at behavioral threshold and 5 dB SL than N1 and P2 late potentials. The P3 was larger in amplitude than either the N1 or the P2 at threshold and for 75 dB SPL stimuli. In comparing P3s obtained at threshold and for the 75 dB stimuli, significant effects were noted in latency and amplitude reflecting exogenous aspects to this endogenous potential. Differences in latency and amplitude were also noted in N1 and P2 waveforms obtained from the rare versus frequent stimuli. Clinical implications of these results are discussed.

“…Distúrbios das funções musicais, principalmente referindo-se aos aspectos ritmo e melodia, têm sido observados quase que exclusivamente em pacientes afásicos, portadores de lesões cerebrais lateralizadas e extensas 5,[31][32][33] . As habilidades musicais podem permanecer preservadas na ocorrência de distúrbios da linguagem e, portanto, a existência de dissociação entre distúrbios musicais e verbais sugere uma independência funcional relativa de substratos neurobiológicos para cada atividade 1,3,7 .…”

Foram avaliados 14 pacientes destros com idade mediana de 30 anos, portadores de epilepsia parcial (Grupo Epiléptico) e divididos em dois Grupos (Direito e Esquerdo), segundo a lateralização da atividade paroxística no eletrencefalograma interictal. Dos 14 pacientes, 42,8% (6/14) dos casos apresentaram foco à direita, enquanto os 57,2% (8/14) restantes apresentaram foco à esquerda. O Grupo Controle foi formado por 31 indivíduos destros com idade mediana de 30 anos e sem história de doença neurológica ou antecedente de crises epilépticas. Os indivíduos estudados, sem conhecimento musical, realizaram Testes de Habilidades Musicais que envolveram Ritmo Espontâneo, Percepção dos Parâmetros Musicais (timbre, duração, altura, intensidade e ritmo) e Testes Gnósico-Práxicos (reconhecimento e reprodução de parâmetros musicais e organização e reprodução de movimentos corporais rítmicos). Concluímos que a presença do foco no hemisfério cerebral direito afeta o desempenho de funções de reconhecimento melódico, enquanto que nos casos com foco no hemisfério cerebral esquerdo, a reprodução e organização rítmicas estão mais comprometidas quando comparados ao Grupo Controle.
