These courses are to prepare EEG Technologists for the credentialing exam in Long Term Monitoring and Continuous EEG monitoring in the Intensive Care Unit. The CLTM exam also includes Monitoring during Cortical Mapping, Electrocorticography, and Cortical Stimulation topics.  Be sure to include IONM 110 to your board preparation plans. Important: For more in-depth study of electrocorticography and functional brain mapping see IONM - 110 under the IONM courses.  There is some cross over of IONM and LTM when the patient goes into surgery.  Electrocorticography and functional cortical mapping is covered in the ABRET CLTM and CNIM exams.
