Overview
This study aims to investigate that neural activity of higher cognitve function of human brain with hyperflexible neural electrode-cortex
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.
Eligibility
Inclusion Criteria:
- aged 18-70 years old.

- volunteered to participate in this study and sign informed consent.
Exclusion Criteria:
- have severe cognitive dysfunction.
- have psychiatric disorders, such as depression, anxiety disorders and schizophrenia.

- be allergic to surgery instruments or medications.
- have general anesthesia, surgery contraindications.
- have acute cardiac infarction or heart arrest within 6 months.
- have other neurosurgery contraindications assessed by investigators.
- lactation or pregnancy.
- have serious systemic disease or organ dysfunctions that affects study outcome or visits.
