fMRI is good at using this resolution to measure brain activity
What is good spatial resolution?
An EEG, or electroencephalography, directly measures this by placing electrodes on the scalp to detect signals from populations of neurons under the skull
What is neural activity?
This indirectly measures neural activity by measuring the amount of blood flow to various brain areas. More active areas of the brain use more blood. The powerful magnet in the machine makes the hemoglobin molecules in the blood all orient in the same direction. After high-resolution images are procured, mathematical models are used to build a clearer picture of the activity.
What is fMRI?
This group is used when researchers want to see if there’s a difference in neural activity when the same groups of people do multiple tasks.
What is tasks logic?
Researchers use fMRI to compare this within expected areas (i.e. amygdala) across two experimental conditions
What is brain activation?
ERP is often used in diagnoses of this in neural activity. By applying specific kinds of stimulus, it can be determined if there is this activity by comparing the results to the known responses to the cognitive processes tested
What are abnormalities?
This measures the activity of neurons in a specific location in the brain when a stimulus is applied.
What is EEG?
This group is used to see if there is a difference in neural activity between different groups of people doing the same task
What is groups logic?
This is an average of the EEG data, measuring the response to that specific stimulus.
