Abstract: Electrically excitable cells are present in many multicellular organisms, especially in brains of animals, but they are also present in lower animals lacking central nervous system as sponges or in animals having excitable epithelia, which can conduct signals (neuroid conduction). Conducted electrical events serve for translation of environmental parameters and cues, obtained via sensory systems, into biological information and processes. Living organism uses electric signal to encode sensory information and prepare it for further processing what results with a specific actions (behaviour) or with memory storage in cellular network. Understanding of physical basis of information processing in living organism is an important aim of the modern neuroscience. The most common way for uncovering the response organization is observation of cell cultures under particular conditions. Such conditions can refer to different type of environmental stimuli, like chemicals, temperature, light intensity including gravity. The main aim of the project is the study of, through the model systems, the ability of living organisms to adapt to a new environment in terms of a proper information processing of external stimuli and memory processes.
