Abstract Background Brain tumor surgery is limited by the risk of postoperative neurological deficits. Intraoperative neurophysiological examination techniques which are based on the electrical excitability of the human brain cortex are thus still indispensable for surgery in eloquent areas such as the primary motor cortex Brodman Area 4 . Methods This study analyzed the data obtained from a total of 255 cerebral interventions for lesions with direct contact to 121 or immediately adjacent to 134 Brodman Area 4 in order to optimize stimulation parameters and to search for direct correlation between intraoperative potential changes and specific surgical maneuvers when using monopolar cortex stimulation MCS for electrocortical mapping and continuous intraoperative neurophysiological monitoring. Results Compound muscle action potentials CMAPs were recorded from the thenar muscles and forearm flexors in accordance with the large representational area of the hand and forearm in .
