S.K. Rosahl, N. Creutzburg, A. Langbein & R. Gerlach
Objective: Recording of muscle action potentials (MAP) evoked upon electrical stimulation is the method of choice for intra-operative mapping of the cranial nerves in surgery for lesions around the brainstem and at the skull base. Waveforms and thresholds of these MAP vary depending on the nerve to [for full text, please go to the a.m. URL]
