Study Notes
Neuroimaging Techniques
- Electroencephalography (EEG) has excellent temporal resolution, allowing it to measure neural activity on a millisecond timescale.
- Functional magnetic resonance imaging (fMRI) measures changes in blood oxygenation levels to infer brain activity, providing a indirect measure of neural activity.
- EEG is commonly used in clinical settings to diagnose epilepsy, as it provides a non-invasive and cost-effective way to measure abnormal electrical activity in the brain.
- Magnetoencephalography (MEG) has relatively poor spatial resolution due to signal distortion passing through the skull and scalp, making it less accurate for localizing brain activity.
- EEG records the summation of postsynaptic potentials from thousands of neurons, providing a measure of neural activity at the scalp level.
