Great discoveries solve problems in different, scientific fields.

Interference Networks
Note
The circuits shown here as interference networks are not electrical networks, but rather nervous networks with extremely low conduction velocities! All lines are delay lines. The electrical node abstraction of a line is not valid. Time is required to overcome any distance!
Early Investigations
After the idea of interference networks was born in 1992, the first experiments showed that no "spiking" data can be obtained from the nervous system using high-channel and non-invasive methods. So we looked for a new idea. For this purpose, an 8-channel EEG data recorder was converted to microphones. The software "Bio-Interface" promptly delivered the first acoustic (still) image (1994). Afterwards we noticed that hundreds of acoustic institutes worldwide worked in this field.

Discovering the Nerve System
How to understand holomorphic brain projections? Simulations of interference nets in nerve like parametrisation show well known phaenomena: mirrored maps, bursts, conjunction, zooming, movement, pain overflow or dermal projections (somatotopy). We simulate the homunculus and we find ideas for imagination and holomorphy. Is it coincidence or providence?
Is there an approach to understanding our holographically organized nervous system? The first simulations of interference networks in nervous parameterization show well-known phenomena: reflective maps, holographic properties, pulse series (bursts) as codes, image fusion, image zoom, image movement, pain overflow or skin projections (somatotopy). We simulate the homunculus and find ideas for visual imagination.

Acoustic Photo- and Cinematography
Birth of a new technology: acoustic photo and cinematography (Acoustic Camera). Far from the mainstream of acoustic research, this crazy idea was designed in 1994 to demonstrate how interference networks could project images (with inversive time or with non-causal, negative delays).
