1. The technology is called electrocorticography, or ECoG, and it uses electrodes placed on the surface of the brain to detect electrical signals coming from the brain itself.

2. Objective To investigate the effects of electrocorticography ( ECoG ) monitoring in microsurgical treatment of intracranial cavernous hemangiomas ( ICH ) .

3. Conclusion: Surgical treatment for intractable post-traumatic epilepsy with electrocorticography monitoring was proved more effective and safe.

4. A typical Electrocorticography (ECoG) based invasive BCI system was off-line analyzed in this paper.

5. Results The established diagnosis of the brain tumors could be removed without electrocorticography during the operation with 77. 89% elimination rate of epilepsy.

6. Objective To investigate the indications, technical considerations, and effects of neuronavigation and electrocorticography (ECOG) monitoring in resection of brain cavernous malformations (CM).

7. Conclusions DNT is benign tumor which could be treated by surgery, total removal of tumor and using intraoperative electrocorticography could improve the result of operation.
