| 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. |
