Abstract		Neural networks represent a system-model consisting of elements (formal neurons), which are tightly linked. Especially in the last decade (after the development of associative neural networks) this model has become interdisciplinary importantat researches of collective parallel-distributed processes, also under the cover of synergetics. In this article brain-modeling with neural networks (especially associative neural networks - Hopfield- and Haken-model) is introduced with the stress on thought processes. The article shows how nervous cells (neurons), or rather their configurations of activity, form the patterns, which then structurize themselves hierarchically. Patterns and their clusters represent Gestalts of various degrees; associative relations and chains among them being the basis for mental processes. "Order parameters" corresponding to hTgher patterns have the function of active codes, which are driving-wheels of the (re)construction of patterns (schemata, symbols, archetypes etc.) and their semantics. It is explained how memory-traces of patterns are loaded into synaptic bonds, enabling them to be simultaneously stored. Correlations among patterns are the fundamentals of memory; associative contextuality being the origin of the so-called subjectivity on the higher level. The "key elements" of understanding and self-regulatory mechanism such as learning, selectivity, adaptivity, attention, ambivalence, generalization- and abstracting-ability etc. are discussed. Furthermore, analogies with sociological and physical systems are indicated. Special emphasis is placed on the necessity of researching the entire system and its differentiated virtual niveaus as an indivisible co-dependent whole.
