Summary

Automatic Translation

Métodos eEG são aplicados para extrair biomarcadores de disfunções cerebrais. O foco está nos potenciais relacionados a eventos multicanais (ERPs) registrados em uma tarefa GO/NOGO. Artefatos não cerebrais são corrigidos e os ERPs são comparados com os dados normativos. Exemplos referem-se a biomarcadores para diagnóstico de TDAH e previsão de resposta a medicamentos.
