"Intraoperative neurophysiological monitoring" is a mouthful of a term that can be hard to remember and even harder to pronounce. Fortunately, there are some alternatives you can use to make things easier. One option is to refer to the process simply as "neuromonitoring," which gets the point across without all the extra syllables. Another synonym you might consider is "intraoperative neurological monitoring," which retains the medical specificity of the original phrase while still being simpler to say. You could also use the term "neurosurgical monitoring," which highlights the fact that the process is focused on surgical procedures involving the nervous system.
