To minimize permanent postoperative deficits, functional mapping with direct electrical stimulation (DES) is  becoming a  gold standard when a  brain tumor resection must be performed near or  within eloquent areas. Due to the devastating impact of communication disabilities, language is one of the most commonly mapped functions. However, standardized linguistic protocols for intraoperative use are still scarce. Here we present the first Russian standardized naming test for mapping noun and verb production during awake neurosurgeries. Its development has been informed by modern (psycho)linguistic knowledge and DES requirements. The test was clinically piloted in a sample of 23 patients who underwent awake craniotomy, with results showing high relevance of the test in combination with DES for mapping language-relevant cortical and subcortical sites. The use of the test intraoperatively enabled extensive resection of tumor tissue while preserving language function in most of the tested patients. The test materials and protocols are freely available online.
