- Studying the brain
- Functional Magnetic Resonance Imaging (fMRI)
- Detects changes in blood oxygenation and flow as a result of neural activity in parts of the brain
- When a brain area is more active it consumes more oxygen
- To meet the increased demand, blood flow is also directed to that area
- Known as the haemodynamic response
- To meet the increased demand, blood flow is also directed to that area
- Produces 3 dimensional images (activation maps)
- Shows which part of the brain is involved in a particular mental process
- Electroencephalogram (EEG)
- Measures electrical activity in the brain via electrodes that are fixed to individuals using a skull cap
- Scan recording represents the brainwave patterns that are generated from the action of millions of neutrons
- Providing an overall account of brain activity
- Scan recording represents the brainwave patterns that are generated from the action of millions of neutrons
- Often used by clinicians as a diagnostic tool
- Unusual arrythmatic patterns may indicate neurological abnormalities such as epilepsy, tumours or sleep disorders
- Measures electrical activity in the brain via electrodes that are fixed to individuals using a skull cap
- Event-Related Potentials (ERPs)
