The story of information processing is a story of great success. Todays'
microprocessors are devices of unprecedented complexity and MOSFET transistors
are considered as the most widely produced artifact in the history of mankind.
The current miniaturization of electronic circuits is pushed almost to the
physical limit and begins to suffer from various parasitic effects. These facts
stimulate intense research on neuromimetic devices. This feature article is
devoted to various in materio implementation of neuromimetic processes,
including neuronal dynamics, synaptic plasticity, and higher-level signal and
information processing, along with more sophisticated implementations,
including signal processing, speech recognition and data security. Due to vast
number of papers in the field, only a subjective selection of topics is
presented in this review
