Abstract

Computerized tomography (CT) and magnetic resonance imaging (MRI) are excellent techniques for studying structural brain anatomy. Positron emission tomography, regional cerebral blood flow, and single photon emission CT (PET, RCBF, and SPECT) reveal brain function but suffer from the disadvantage of being invasive and requiring the subject to maintain a particular position for a relatively long period of time. These latter disadvantages are problematic when dealing with hallucinatory patients. In contrast, the electroencephalogram (EEG) has an extremely short analysis time and is not invasive. Our investigations involve EEG mapping, which allows display of the topographic distribution of functional states of brain electrical activity. The aim was to demonstrate topographic changes in the EEG caused by hallucinations.
