What neuroimaging techniques involve the electrical component of neural transmission?
(34) 
Answered by Examlex AI CopilotNeuroimaging techniques that involve the electrical component of neural transmission primarily include electroencephalography (EEG) and magnetoencephalography (MEG). These techniques are used to measure and record the electrical activity generated by neurons in the brain.
1. Electroencephalography (EEG): EEG is a non-invasive method that captures electrical activity through electrodes placed on the scalp. The technique detects fluctuations in voltage resulting from ionic current flows within the neurons of the brain. EEG is widely used for diagnosing epilepsy, sleep disorders, and for research in cognitive neuroscience to study brain function during various tasks.
2. Magnetoencephalography (MEG): MEG measures the magnetic fields produced by neural activity. It is similar to EEG in that it tracks the dynamic processes within the brain, but it detects the magnetic signals associated with these electrical currents. MEG provides a more direct measure of neural activity than EEG and has a higher spatial resolution, making it useful for pinpointing the sources of activity within the brain.
Both EEG and MEG are valuable for studying the timing (temporal resolution) of neural processes, which is crucial for understanding how the brain functions in real-time. However, they are less effective for pinpointing the exact location of activity within the brain (spatial resolution) compared to other neuroimaging techniques like functional magnetic resonance imaging (fMRI) or positron emission tomography (PET), which measure changes in blood flow or metabolism associated with neural activity.
