question
single-unit recording method,
answer
hin microelectrode is surgically inserted in or near an individual neuron, is used primarily with animals.
question
electroencephalograph (EEG).
answer
an instrument that records the electrical activity produced by the brain's neurons through the use of electrodes placed on the surface of the research participant's head
question
positron emission tomography (PET) scan
answer
an invasive imaging technique that provides color-coded images of brain activity by tracking the brain's use of a radioactively tagged compound, such as glucose, oxygen, or a drug that has been injected into a person's bloodstream
question
Functional magnetic resonance imaging (fMRI)
answer
a type of brain scan that uses a magnetic field to create images of brain activity in each brain area.
question
A noninvasive neuroimaging technique that produces very clear and detailed images of the structures and activities in the brain in response to magnetic fields is called _________________.
answer
functional MRI
question

answer
electroencephalography (eeg)
question
