Solution Preview

In the cognitive sciences brain scan imaging is done by magnetic resonance Imaging (MRI), functional magnetic resonance imaging (fMRI), magnetoencephalography (MEG), and event-related potentials (ERPs). They are used when recording brain activity and correlating the activity patters with behavior. They have been used to determine:
? how areas of the brain are involved in motion or color perception
? the selection or generation of actions
? language processing
? imagining
Other studies have been done using brain imaging on the temporal nature of processing of different stimulus properties or response patterns in vision, attention, and memory. The temporal and spatial maps of brain functions, the "what" and "where" of these processes have been combined in MEG studies and in event-related fMRI.

Neuropsychological studies of patients had been hampered for many years by the inability to locate precisely the brain lesions in some patients. With anatomical MRI a patient's lesions can be seen according to the ...

Solution Summary

Studies done using brain imaging have shown that particular areas of cerebral dysfunction may facilitate violent outbursts through various mechanisms.
