Document Summary

Technologies and methods that enable scientists to generate functional maps of brain activity through measurements of changes in either the brain"s metabolism, blood flow, or electrical activity. Assess the functional and metabolic activity of brain. Electrodes placed on the scalp: generates maps of neural activity. Eeg (spontaneous electroencephalography): measure rhythms of electrical activity of neurons under stimulus conditions. Erp (event-related potentials): measures electrical activity of specific brain areas in response to a particular stimulus of actions. Meg (magnetoencephalography): magnetic field generated by electrical currents are detected by sensors on scalp - doesn"t distort like eeg and erp. Assessing the brain"s anatomical structure (i. e. checking for a missing part of the brain or a brain tumor) Mri (structural magnetic resonance imaging): anatomical structure of the brain is imaged by the created of a large magnetic field that interacts with molecules in the body - non-invasive, no radiation, harmless.
