Ways of investigating the brain Flashcards
fMRI
A method used to measure brain activity while a person is performing a task that uses MRI technology . This allows researches to detect the changes in blood oxygenation and locate which region are rich in oxygen and thus are active.
EEG
measures electrical activity within the brain via electrodes attached to the scalp it records tiny electrical impulses produced by the brain’s activity. By measuring characteristic wave patterns, the EEG can help diagnose certain conditions of the brain.
ERPs
The brain’s electrophysiological response to a specific sensory, cognitie or motor event can be isolated through statistical analysis of EEG data
Post-mortem examinations
The brain is analysed after death to determine whether certain observed behaviours during the patient’s lifetime can be linked to abnormalities in the brain.
