Abstract

The aim of this work is to describe, using functional imaging techniques, the spatial and temporal distribution of neural activations ensuing from execution of cognitive functions and to find correlation in data coming from analysis modalities related to different physical properties. A 10-min continuous performance test (CPT) was administered to a group of healthy subjects as measure of sustained attention. Images of Electroencephalography (EEG) and of Near Infrared Spectroscopy (NIRS) were recorded during the task. Cerebral activation's measure is obtained from the recording of quantities linked with electrical neural activity for the EEG and with change in blood oxygenation for the NIRS system. Good agreement was found between the two modalities, both showing higher activation in the middle upper frontal region and similar temporal trend. A further understanding of the superior central nervous system behavior can be achieved from combined use of both imaging modalities.
