Abstract
Background
Various neuroimaging studies, both structural and functional, have provided
support for the proposal that a distributed brain network is likely to be
the neural basis of intelligence. The theory of Distributed Intelligent
Processing Systems (DIPS), first developed in the field of Artificial
Intelligence, was proposed to adequately model distributed neural
intelligent processing. In addition, the neural efficiency
hypothesis suggests that individuals with higher intelligence
display more focused cortical activation during cognitive performance,
resulting in lower total brain activation when compared with individuals who
have lower intelligence. This may be understood as a property of the
DIPS.
Methodology and Principal Findings
In our study, a new EEG brain mapping technique, based on the neural
efficiency hypothesis and the notion of the brain as a
Distributed Intelligence Processing System, was used to investigate the
correlations between IQ evaluated with WAIS (Whechsler Adult Intelligence
Scale) and WISC (Wechsler Intelligence Scale for Children), and the brain
activity associated with visual and verbal processing, in order to test the
validity of a distributed neural basis for intelligence.
Conclusion
The present results support these claims and the neural efficiency
hypothesis.
