Brief Summary
The study aims at constructing a Chinese language probabilistic map by awake intraoperative direct electrical stimulation (DES) language mapping. At the same time, the standardization and optimization of awake intraoperative DES parameters will be explored, factors affecting postoperative function morbidity and survival will also be analyzed.

Outcome Measures
Primary Outcomes (1)
Incidence rate of postoperative language deficits
Language deficits were considered when the participant presents with aphasia or severe dysphasia measured by standardized Aphasia Battery of Chinese (ABC, a Chinese version of Western Aphasia Battery) having the Aphasia Quotient (AQ) less than 50 (where lower values represent a worse outcome).
The first month and the third month after surgery
Secondary Outcomes (3)
Location of positive sites in cortical mapping
During surgery
Incidence rate of intraoperative epilepsy induced by direct cortical stimulation
During surgery
Extent of resection
Within 72h after surgery
Study Arms (1)
Direct electrical stimulation
EXPERIMENTALIntraoperative direct cortical electrical stimulation or intraoperative direct subcortical electrical stimulation on language or language-associate areas, and the participants' after-discharge activity would be monitored. The participants would be undergone awake anesthesia and asked to perform language tasks during the stimulation.
Interventions
Intraoperative direct electrical stimulation on language or language-associate cortex, was performed using a 5-mm wide bipolar electrode with a pulse frequency of 60 Hz and an amplitude of 1.5 to 6 milliamperage. The somatosensory evoked potential was recorded with a 6-contact subdural strip electrode. If after-discharge activity indicated that the stimulation current was too high, the current amplitude was decreased by 0.5 to 1 milliamperage. The participants would be undergone awake anesthesia and asked to perform language tasks during the stimulation.
Intraoperative direct electrical stimulation on language or language-associate subcortical pathways, was performed using a biphasic square-wave pulse delivered at 60 Hz with a current amplitude ranging from 1.5 to 10 milliamperage. The somatosensory evoked potential was recorded with a 6-contact subdural strip electrode. If after-discharge activity indicated that the stimulation current was too high, the current amplitude was decreased by 0.5 to 1 milliamperage. The participants would be undergone awake anesthesia and asked to perform language tasks during the stimulation.
