Als ich 18 war, kaufte ich mir ein Elektroenzephalograph, ein EEG, ein Gerät, das Gehirnströme mißt.

Ich wollte damit ausschließlich Kunst machen und habe damit fast zehn Jahre Lang Projekte im Medien -Kunstbereich realisiert.

Die Krönung meiner Gehirnwellprojekte war dann, als ich zusammen mit Jaanis Garancs, Norman Muller und Sven Hahne BIOS realisiert habe. Die Projekt Homepage ist hier zu finden.:

Es war eigentlich schon damals klar, dass man durch eine sehr genaue Echtzeit Analyse der Gehirnströme die Bilder rekonstruieren könnte, die der Mensch gerade sieht. Dies wurde erst 2022 durch den Einsatz von künstlicher Intelligenz praktisch zum ersten Mal erfolgreich umgesetzt .Das war aber bereits damals meine grundlegende Annahme aufgrund der Retinotopie.


In the course of history there have been many attempts to understand the way images are processed until finally they appear as ”impressions” in the mind. Due to the lack of sufficiently sensitive sensors (and maybe also for pragmatic reasons), one of the first experiments involved showing a certain picture to a macaque monkey and subsequently shock-freezing the animal. After that, its brain was removed in what was hoped to be the state ”identical” with the moment of discrete perception. Because the monkey was previously injected with a radioactive fluid, it was possible to produce an X-ray exposure showing a distorted version of the picture found in an area at the rear of the brain. Other perception-capture experiments were made by attaching invasive electrodes directly to the retina of a cat’s eyes. The result was a very noisy black-and-white video; the resolution was very poor, but the origin remained clearly recognizable. These are just two examples of the ”normal” methods still used by neurologists. We therefore did not want our apparatus to have the clean, highly polished appearance that commercial companies would prefer for their images. Instead, the visitor ought to receive some sensation of how one of the countless test monkeys might have felt before perishing in the course of the scientific quest to create the theoretical basis for our machine. However, we did not build our apparatus solely in order to protest against such experiments. It also has a deep connection to the old philosophical problem of reality, or more precisely, of distinguishing between what is ”real” and what is ”hallucination.”












Because the transformation of light energy into the language of the brain takes time, our seeing is always delayed. The visual and aural impulses emitted by a nearby object reach our brain at different times. Thus, due to the divergent temporal performance of our sensory organs, events that are objectively simultaneous are subjectively dislocated in time. Although these differences are very slight in terms of human perception, use of the term "simultaneous" is justified neither in the physiological nor quantum-mechanical sense. Everything that one sees, hears, smells and feels occurred prior to our perception of it. In other words: We "scan" reality in similar fashion to the frames of a film. A feeling of time is generated by the clocking of this scanning, by the density of registering modifications. It is very evident how dependent perception is on the biological condition of the perceiving creature. A cold lizard perceives time more slowly than does a warm one. In stressful situations, time seems to pass faster than when we are enjoying a peaceful rest. Besides the above problems, one runs into real, and not purely linguistic, difficulties when trying to decide if it would be possible to distinguish between a simulation of all senses (by some kind of machine not yet invented) and the ”real” world. At the moment, we are remote from building such a machine, but we imagine that at least some of our readers have had dreams in which they touched, heard, saw or even smelled things as vividly if they were awake. One possibility of gaining a sense of what perceptional interpretation means would be to amplify it. In other words: If we found a way of tapping the perceived signal after its transformation, then it could be ”fed back” in order to be transformed again, and this re-transformation would be repeated an undefined number of times and amplified in the process. Basically, that is what BIOS does. The Apparatus An exterior audiovisual perception path forming a closed loop with the natural path is generated. The viewer is invited to immerse himself in his own (physiological) perception. The attached electrodes transfer to an electroencephalograph (EEG) signals from the three sensory areas of the brain cortex, namely the visual cortex V1 along with the two auditive cortices






A custom-built interface translates the voltage curves of the EEG into binary data. Thus it is possible to algorithmically ”re-translate” this information into audiovisual signals. As output media, the HMD, and the headphones represent the electromechanical part of the cycle. The output continuously runs (back) into the biological perception apparatus, resulting in the development of feedback. The neurological term ”Retinotopie” describes the pattern of projection, the way the X/Y position of one point in the visual field is represented on the surface of the first visual cortex. On the basis of the X/Y position and frequency of an electrode, the computer calculates the X/Y position and color of a pixel in the resulting image. The time flow is represented by the Z (depth) value. Missing intermediate values are interpolated (synthesized). The accompanying image shows the system of conversion (that is to say: basic principles). For BIOS we took the artistic liberty of visualizing ”output” as subtly colored pulsations and waves of light. In the stereoscopic HMD, these trembling, breathing, flowing flares sometimes rouse visual associations with fire, smoke and liquid. They also bear some resemblance to the images seen if one presses the fingers against one's eyes. [*the following paragraph could be skipped - if there is not enough space*] The auditory cortex is similar, but somewhat more simple, in its pattern. The cochlea forms a spiral structure behind the ear. Sounds are translated to the biological cognitive system by the movement of finest villi which emit neuronal impulses. Each villus has a nerve connection leading to the acoustic cortex, which is again spiral in form. If we imagine the cochlea to be placed directly on top of the auditory cortex, then the connections would be parallel. Three signals are received, corresponding to basses, middles and trebles. The conversion corresponds to a Fourier (algorithmic) analysis, which is interpolated to the original width and re-synthesized afterwards. BIOS team More information on the project available at The above description conveys the current state of the project (2002/2003). Enhanced versions of BIOS involving more advanced hard- and software for audiovisual cortex-pattern recognition and set-up (improved for visitors) are in development.


I am currently working on a #Neuro_Abundance_Manifest.
#Neuro Abundace Manifest
#AI #neuro #neurodivergent #Neuroscience#neurodiversity
2000 ! i had the original idea -and had the neccessary EEG .,-

I knew this would be technically possible !!!!!!
and : 2023
my basic assumption was proven RIGHT !!!!!!!!!!!!!!!!!!!!!

Since i knew 2000 already this will principally work i will now also call my selve the #inventor of #Neuroart and #brainwaveentrainment#brainwave_music

with the kind help of Jaanis Jānis Garančs Sven Hahne and Norman Muller who built the helmet and the great support of Prof Dr Zielinsky and KHM and MIT my basic assumption is now PROVEN right and #TTrue
