Interference-Measurement with PSI-Tools

(PSI: Parallel and Serial Interference) Taking into account, that the possibility to excite a neuron is as higher, as more closed some input impulses arrive, delays, wire lenghts and circuit geometries become strong influences on the logical function of a pulse-propagating circuit. The properties of known logic circuits are dismissed: logic function becomes a function of the location even as a function of type, weights and thresholds.

To research different geometries together with different time-functions, we designed this special software tool. The Interference Assistent combines two elementary, incremental neural spaces together, each supposed to have a homogenous excitement speed. We call this spaces generator and detector.

Both spaces are coupled via channels. It is possible, to define individual delays for each channel wire. Time-functions flowing through channels can be stored as channel data stream files. Also it is possible, to load external channel data, for example comming from EEG-devices. The tool physical has an A/D- and D/A-converter port. Channel data physical can be taken from an 16 input-ADC with preamplifiers. Gain, pass band, test-signals and working modes of the preamplifiers are digital controlled and initialized per software. Thus all values are reloaded while initialising the preamplifiers.

Each interesting point (neuron) of both spaces is supposed to have straight, physical connections to each electrode of the space. Wires and distances are supposed to have a length proportional delay (constant excitement speed is supposed).

It is possible, to implement bitmaps with black and white pixels into the generator space. Black pixels have the task, to send on different conditions time-functions (impulses) into the space. White and coloured pixels remain still. Also it is possible, to use mathematical function generators instead of bitmaps.

The detector space ever lays virtual on the PC. We only consider the connectivity between a neuron on a defined location and the electrodes. It is possible, to calculate different neural combinatory functions, like addition, multiplication and different thresholds and threshold functions.
