The Brain in Probabilistic Hyperspace

Abstract

The transfer function describes the ability of a network to increase or impede transmission of signals in given frequency channels. The transfer function, represented mathematically by frequency characteristics or wavelets, constitutes the main framework for signal processing and communication (see Chaps. 6–8). The existence of general transfer functions would then be interpreted as the existence of networks distributed in the brain having similar frequency characteristics facilitating or optimizing the signal transmission in resonant frequency channels (Başar 1998). In an electrical system, an optimal transmission of signals is reached when subsystems are tuned to the same frequency range. Does the brain have such subsystems tuned to similar frequency ranges, or do common frequency modes exist in the brain?
