Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this study, patients who need intracerebral puncture and indwelling drainage tube, such as intracerebral hemorrhage and hydrocephalus, will be recruited. Before implanting electrodes, patients will be trained to do higher cognitive function tasks.During operation, electrode will be implanted accompanied by placing drainage tube. After operation, patients will perform tasks, while electrophysiological signals will be collected. At the end of study, electrode will be removed.
