Models of Brain Processing with Respect to Functional Neuroimaging
The cerebral cortex contains approximately 1014 synapses (von der Malsburg and Singer 1988). Current neuroimaging techniques can only resolve brain regions containing millions of cells. Hence it is always the coordinated functioning of millions of synapses and neurons that generate measurable activity. A single neuron cannot alone accomplish the processing from which complex behaviours emerge. Thus, in attempting to understand the neuronal basis of complex behaviour it is essential to have a theoretical model of the interactions of large groups of functional units. This not only makes data management convenient; it also in some way represents biological reality.
