The possibility to excite any neuron is higher if different excitements reach it in the same time. But every excitement is delayed by different circumstances on different paths.
The abstraction ‘Interference Network’ (IN)

allows the analysis and simulation of complex, delaying networks without too much knowledge about details. A graph of the three-dimensional structure with delays, with neuronal time-functions and with integration behaviour offers a lot about the general behaviour of a nerve net.
For example we will find that the delay structure of a large net defines different excitatory and inhibiting possibilities, resulting in signal-theoretical descriptions of neural functions, compare to

Implementing the term “Interference Integral” (I²), relations between emitting source points and receiving source points can be found. Interference projections for far communications over long fibres can be understood in optical-like relations: the interference integrals appear mirrored, comparable to lens projections, if we suppose single impulses or long intervals between pulses. Analysing meeting points of periodical waves, we find a kind of frequency maps, see

In the sight of IN, the difference between to see and to hear results only in different network parameters. A specific investigation of such parameters offers, that both possibilities match in a holomorphic way. Projections and frequency maps, seeing and hearing are organized in hologram-like structures, compare with a 3-channel interference projection of G-like arranged emissions

Analysing the influence of velocities on long fibres, we detect a possibility to move the projections on a neural ‘screen’. Analysing changing field velocities, we find zooming projections,

Combining fibres from different sources, the interference integrals merge, see

Reasoned by phase-invariants, a field theoretical investigation shows, that interference networks disrupt the range of complex number theory in real applications. That means that Fourier-, Wavelet- or Gabor- Transformations can not be applied for the analysis of nerve networks. But not only interferences in nerve nets, also quantum field analysis are concerned.
