Study Overview
Brief Summary
This study aims to investigate that neural activity of higher cognitve function of human brain with hyperflexible neural electrode-cortex
Detailed Description
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.

Outcomes
Primary Outcomes
recording single neural spikes
Time Frame: through study completion, an average of 2 year
The mechanism of higher cognitive functions will be investigated by analysing characteristics of single neural spikes which is correlated with higher cognitive functions tasks, such as firing frequency, events related potential, information coding, etc.
recording local field potentiation
Time Frame: through study completion, an average of 2 year
The mechanism of higher cognitive functions will be investigated by analysing characteristics of local field potentiation which is correlated with higher cognitive functions tasks, such as events related potential, information coding, etc.
Secondary Outcomes
No secondary outcomes reported
