“…This is generally related to a reorganization of language after the vascular event [23][24][25][26] . These differences in degree and functional pattern are due to the interaction of multiple factors, including the localization, extent and type of injury, age at onset, epilepsy and integrity of surrounding and contralateral brain areas 2,[24][25][26] . Usually, lesions involving the anterior and posterior temporal lobe result in inter-hemispheric reorganization and consequent reversal of dichotic verbal asymmetry, as seen in S13.…”

“…Usually, lesions involving the anterior and posterior temporal lobe result in inter-hemispheric reorganization and consequent reversal of dichotic verbal asymmetry, as seen in S13. Small perisylvian lesions can be followed by intra-hemispheric reorganization, and thus the right ear advantage is maintained 24,25 . In some patients in the SG, these areas were spared and, in these, attenuation or even reversal of the right ear advantage could be a result of the reorganization of subcortical auditory structures, or changes in subsequent stages of cortical processing 27,28 .…”

OBJECTIVE: To verify the auditory selective attention in children with stroke. METHODS: Dichotic tests of binaural separation (non-verbal and consonant-vowel) and binaural integration - digits and Staggered Spondaic Words Test (SSW) - were applied in 13 children (7 boys), from 7 to 16 years, with unilateral stroke confirmed by neurological examination and neuroimaging. RESULTS: The attention performance showed significant differences in comparison to the control group in both kinds of tests. In the non-verbal test, identifications the ear opposite the lesion in the free recall stage was diminished and, in the following stages, a difficulty in directing attention was detected. In the consonant- vowel test, a modification in perceptual asymmetry and difficulty in focusing in the attended stages was found. In the digits and SSW tests, ipsilateral, contralateral and bilateral deficits were detected, depending on the characteristics of the lesions and demand of the task. CONCLUSION: Stroke caused auditory attention deficits when dealing with simultaneous sources of auditory information.

“…The findings of the perceptual asymmetry inversion constitute classic effect in studies with injured patients under dichotic stimulation. Literature has related this asymmetry as resultant of multiple factors, as age, type, localization and extension of the injury, cerebral state prior morbidity, conditions of the neighboring and contra-lateral injury areas, therapies received, among others, acting in a cascade effect on the cerebral reorganization (6,18). In extensive injuries of left hemisphere, the verbal function can be reorganized in the opposing hemisphere, and in a sequence, a new standard is established having the exchange of the advantage direction.…”

“…Studies have suggested that the type of recovery after injuries varies over the dependence of the affected hemisphere (6,21). Thus, the right hemisphere, more plastic in the compensation capacity, could carry through its original functions and assume the ones from the opposed hemisphere (22).…”

“…In this context, the special hearing tests, widely used in the diagnostic complementation of diverse clinical populations, have contributed in the clarification of the evolution of CVD in adults, adolescents and children (5,6,7). This knowledge is well relevant, particularly in children, given the impact that disorders of this nature can determine in language, not only in acquisition and development, but also in the efficiency and rapidity in daily use and, consequently, in learning.…”

TEMA: na infância a doença cerebrovascular (DCV) constitui condição rara em que a evolução a curto, médio e longo prazo tem merecido esclarecimentos. Neste sentido, a aplicação de técnicas comportamentais pode possibilitar melhor caracterização clínica, visando o planejamento e controle terapêutico eficientes. OBJETIVO: descrever em uma criança com DCV as manifestações audiológicas em dois momentos distintos da evolução clínica. MÉTODO: a criança, com diagnóstico comprovado de episódio único e unilateral de DCV, apresentando habilidades de linguagem e cognição satisfatórias, foi submetida a conjunto de testes convencionais e de processamento auditivo, incluindo a avaliação simplificada e as categorias de testes monóticos, dicóticos e de processamento temporal. Os dados obtidos foram pareados com criança normal destra, de mesmo sexo, idade e nível sócio-cultural. RESULTADOS: foi constatado comprometimento nas habilidades de memória auditiva e atenção seletiva em tarefas de integração e separação binaural para estímulos verbais e não-verbais. CONCLUSÃO: a evolução, embora favorável, se mostrou abaixo do esperado para a idade, quando comparado com seu par. A avaliação prospectiva da criança acometida por DCV possibilitou caracterizar o comportamento auditivo, definir seus parâmetros e a evolução do quadro audiológico.

Early brain lesions and face‐processing development

Studies of functional plasticity after pre- or perinatal brain damage can tell us whether the neural substrate normally involved in the development of a given ability is specific and, if so, when it becomes functionally specified and unique. Development of face processing was investigated in 5- to 17-year-old children who had a unilateral brain injury in the pre-, peri-, or postnatal period. In Studies 1 and 2, patients with a posterior injury involving the temporal regions exhibited a face-processing deficit that was independent of their age at test time. Even though differences were observed between the two hemispheres in face processing during infancy as well as in adults in cases of normal development, no clear differences between right and left injury were observed here in face-processing deficit. Poor postlesional face-processing plasticity seems to contrast with results of several studies on speech development after early unilateral injury. If the difference in the time window for postlesional plasticity between these two areas of competency is confirmed, it would suggest that the two kinds of abilities rely on neural cells which are sensitive to different plasticity factors.
