Structure and dynamics of recurrent neuromodules

The article calls attention to complex dynamical phenomena in arti cial neural systems which are as is asserted of relevance also for understand ing biological brain functions Examples of various dynamical e ects hys teresis oscillations deterministic chaos synchronization and coherence are discussed in terms of the discrete dynamics of small recurrent net works The relevance of a dynamical systems approach for understanding the emergence of higher level information processing or cognitive abilities of biological and arti cial neural systems is discussed submitted for publication
