- Description
Electroencephalograms (EEG) measure and record electrical activity in the brain. Electrodes are attached to the head and hooked by wires to a computer. EEG is noninvasive, radiation-free, and repeatable.The EEG captures a physiological measure of the momentary functional state of underlying cerebral structures. The reconstructed attractor (D"2) is a specific human value for the EEG. Correlations of the EEG's reconstructed attractor are a quantitative characteristic. These are considered a measure of EEG complexity and can be interprated as variability in brain functioning or a correlate of independent cell assemblies number. Variations in underlying neural dynamics have been associated with individual differences in cognition and a number of nueropsychological disorders.
There is a direct relation between EEG complexity and the complexity of behavior in psychosis.
