Brent is taking part in an experiment in a cognitive neuroscience lab. Silently, he reads rapid sequences of words flashed on a
computer screen. The electrical activity of his brain is simultaneously recorded through skull electrodes. The technique used in this study is: Please choose the correct answer from the following choices, and then select the submit answer button. positron emission tomography (PET). magnetic resonance imaging (MRI). functional magnetic resonance imaging (fMRI). an electroencephalograph (EEG).
This is an instrument use in determining or measuring of the electrical activity of the brain. It measures from the surface of the scalp that enables us to measure the generalized activity of the cerebral cortex. Its strength is determined by the amplitude ot he device. It is is used to help diagnose certain neurological conditions that is seizures of epilepsy and for other research purposes.
EEG as it is called for short simply measures electrical activity generated by the brain. It measures the voltage generated as a result of the current that flow during synaptic excitation of the dendrites of many pyramidal neurons in the cerebral cortex that is found beneath the the skull and comprises of most of the brain's mass.
