На кошках изучали соматосенсорные вызванные потенциалы (СВП) спинного мозга при стимуляции периферических нервов в норме и при перерезках дорсальных корешков пояснично-крестцового утолщения. Обнаружено специфическое снижения амплитуд компонентов и локальные сдвиги максимумов на продольном распределении СВП. Сделан вывод, что нарушение проводимости корешков можно изучать путем оценки продольного распределения амплитуд компонентов СВП
