Brain study ways
| Question | Answer |
|---|---|
| EEG | an amplified recording of the waves of electrical activity sweeping across the brains surface. these waves are measured by electrodotes placed on the scalp. |
| MEG | brains imaging technique that measures magnetic fields from the brains natural activity |
| CT | series of x-ray photographs taken from different angles and combined by computer into composite representation of slice of the brains structures |
| PET | technique for detecting brain activity that displays where a radioactive form of glucose goes while the brain preforms a given task. |
| MRI | Technique that uses magnetic fields and radio waves to produce computer generated images of soft tissue. MRI scans show brain anatomy |
| FMRI | technique for revealing blood flow and there fore brain activity by comparing succesive MRI scans. FMRI scans show brain function and structure. |
